Zhong, Chuanrong;Wu, Xiaogang;Wang, Xiangcheng research published 《 Molecular self-assemblies in water and brine and solution properties for a hybrid fluorocarbon surfactant》, the research content is summarized as follows. A novel hybrid fluorinated surfactant, sodium 2-[2-(perfluorohexyl)] acetoxy ethanesulfonate (NaFHAE), was used as a wettability-altering chem. It was desired to reduce the bound water on sandstone and the capillary pressure for water flooding in superlow-permeability sandstone reservoirs. The critical micelle concentrations (cmcs) of NaFHAE were resp. 0.38 and 0.35 g/L in water and brine with 30 g/L NaCl at 30°C. At 0.35 g/L in brine, the contact angle was 68.13°, and the surface and interface tensions were 16.70 and 3.43 mN/m, resp. When 0.2 g/L PS was added to the 0.1 g/L NaFHAE brine, the interface tension decreased sharply from 7.57 to 0.94 mN/m, and the contact angle was unchanged. For the unsalted NaFHAE solution, it was surprising that the addition of PS caused a remarkable increase in the contact angle, especially at 0.1 g/L NaFHAE. The micellization of NaFHAE was entropy-driven, the absolute values of Delta;Gθm were above 35.00 kJ/mol, and the spontaneity of micellization was strong compared to the hydrocarbon surfactants. The diameters of micelles were primarily 30 nm above the cmc in water. UV and fluorescent probe results revealed that the non-polarity of the hydrophobic micro-environment in micelles was weak for hybrid fluorinated surfactants compared with hydrocarbon surfactants and that the sizes of micelles were also affected slightly by salt.

Zhou, Le;Triozzi, Alexandria;Figueiredo, Marxa;Emrick, Todd research published 《 Fluorinated Polymer Zwitterions: Choline Phosphates and Phosphorylcholines》, the research content is summarized as follows. Among zwitterionic structures, the choline phosphate (CP) group is uniquely attractive for its ability to access novel chem. compositions that embed functional groups directly into the zwitterionic moiety. This paper describes the attachment of fluorinated alkyl groups to CP moieties, yielding zwitterionic monomers 1 and 2 that proved amenable to controlled free radical polymerization and the production of a new set of CP-containing fluorinated polymers and copolymers with phosphorylcholine (PC) zwitterions. This combination of fluorinated hydrocarbons and zwitterions affords novel, water-soluble polymeric amphiphiles that we have examined at fluid interfaces, as coatings, in cell culture, and in magnetic resonance imaging.

Zhou, Rong;Jin, Yong;Lai, Shuangquan;Shi, Liangjie;Bai, Long;Peng, Zhangyi research published 《 A novel composite retanning system based on pH-responsive hydrogen bonding and hydrophobic interaction for cleaner leather processing》, the research content is summarized as follows. Aldehyde-tanned leather is one of the promising choices to avoid the widespread chrome pollution in leather industry. Due to the lack of metal ions, the aldehyde-tanned leather not able to effectively fix traditional anionic retanning materials, which seriously affects the quality of aldehyde-tanned leather. Herein, a novel composite retanning system consisting of acrylic resin (AR) and F6-600 (a nonionic fluorinated surfactant with poly(ethylene oxide) (PEO)) was constructed, which breaks through the dependence of conventional leather materials on metal ions in terms of fixation. The main acting mechanism is that at the final stage of retanning, after reducing the float pH, pH-responsive hydrogen bonding and hydrophobic interaction synergistically drive AR/F6-600 to self-assemble into bigger polymer composite aggregates, and then these aggregates are forced to deposit and fill in leather fiber gaps, thus obtaining more desirable retanning results. Furthermore, AR/F6-600 composite retanning system is eco-friendly. The AR/F6-600 retanned leather has lower free formaldehyde content, better biodegradability, and higher uptake rates for subsequent dye and fatliquoring agent, which can further eliminate the threat of formaldehyde to health, accelerate the degradation of waste leather in the nature, and reduce the chem. residual in wastewater, resp. Consequently, this novel retanning system will benefit to satisfy evolving demands for related technologies toward cleaner leather production

Zhou, Rong;Jin, Yong;Shen, Yichao;Lai, Shuangquan;Zhou, Yutang;Zhao, Peng research published 《 Surface activity, salt and pH tolerance, and wettability of novel nonionic fluorinated surfactants with a short fluorocarbon chain》, the research content is summarized as follows. Fluorinated surfactants, especially those with long fluorocarbon chains (C_xF_2x+1, x > 7) like perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are used wildly in industrial and household fields. As research results have shown that such long fluorocarbon chain surfactants are seriously toxic, obviously persistent and highly bioaccumulative in the environment, it is an urgent requirement to develop novel alternatives of the long fluorocarbon chain surfactants. In this work, a series of novel nonionic fluorinated surfactants (FxCy-m) was synthesized by introducing an isophorone diisocyanate unit (as a spacer) between a short hydrophobic fluorocarbon chain (x ≤ 6) and a hydrophilic polyethylene glycol (PEG) chain with a facile two-step couple reaction using com. available reagents. The chem. structures of FxCy-m were characterized by FT-IR and ¹H NMR, and the relationships between length of hydrophilic/hydrophobic chains and surface activity of FxCy-m were systematically investigated by surface tension measurements. Among them, F6C2-400 with a longer fluorocarbon chain and a shorter PEG chain exhibits the highest surface activity, and its capability of reducing surface tension is almost equivalent to that of NaPFO (a derivative of PFOA). Meanwhile, F6C2-400 also has an excellent tolerance to salt and pH as well as an effective wettability. The facile preparation method and the clear structure-activity relationship in our research provide a valuable reference for development of nonionic surfactants with a short fluorocarbon chain.

Zhou, Yutang;Shen, Yichao;Shi, Liangjie;Jin, Yong;Lai, Shuangquan;Tang, Yujia research published 《 Synthesis, characterization and properties of novel nonionic hydrocarbon/fluorocarbon hybrid surfactants containing a short fluoroalkyl chain》, the research content is summarized as follows. A series of novel nonionic hydrocarbon/fluorocarbon hybrid surfactants (Hm-Fn, where m = 10, 12, 14, 16 and n = 4, 6, resp.) were successfully synthesized using polyethylene glycol, isophorone diisocyanate (IPDI), short chain fluoroalkyl alc. and alkyl alc. as starting materials. The preparation process involves the coupling reaction of isocyanate and hydroxyl groups. The surface activity and aggregation behavior of Hm-Fn in aqueous solution were studied by surface tension, steady-state fluorescence and dynamic light scattering (DLS) and transmission electron microscopy (TEM). The influence of the hydrophobic (hydrocarbon or fluorocarbon) chain length on surface activity of such hydrocarbon/fluorocarbon hybrid surfactants was systematically investigated. Micromorphol. anal. revealed the presence of different sizes vesicles in H16-F6 and H16-F4 aqueous solution In addition, the hydrophobic dye solubilization experiments exhibited that H16-F6 with a relatively longer fluorocarbon chain and hydrocarbon chain possessed more outstanding solubilization of model dye (Sudan I) compared with other Hm-Fn and conventional hydrocarbon surfactants. The molar solubilization power of H16-F6 could reach 0.0537. The above results demonstrated that these nonionic hydrocarbon/fluorocarbon hybrid surfactants might possess potential application prospects for hydrophobic dyes solubilization.

Zhao, Nan;Zhao, Meirong;Liu, Weiping;Jin, Hangbiao research published 《 Atmospheric particulate represents a source of C₈-C₁₂ perfluoroalkyl carboxylates and 10:2 fluorotelomer alcohol in tree bark》, the research content is summarized as follows. In this study, we analyzed 30 legacy and emerging poly- and perfluoroalkyl substances (PFASs) in paired atm. particulate and bark samples collected around a Chinese fluorochem. manufacturing park (FMP), with the aim to explore the sources of PFASs in tree bark. The results showed that PFASs in atm. particulate and tree bark samples were consistently dominated by perfluorooctanoate (mean 73 ng/g; 44 pg/m³ ), perfluorohexanoate (47 ng/g; 36 pg/m³ ), perfluorononanoate (9.1 ng/g; 8.8 pg/m³ ), and 10:2 fluorotelomer alc. (10:2 FTOH; 5.6 ng/g; 12 pg/m³). Spatially, concentrations of C₈-C₁₂ perfluoroalkyl carboxylates (PFCAs) and 10:2 FTOH all showed a similar and exponentially decreased trend in both bark and atm. particulate samples with the increasing distance from the FMP. For the first time, we observed strongly significant (Spearmans correlation coefficient = 0.53-0.79, p < 0.01) correlations between bark and atm. particulate concentrations for C₈-C₁₂ PFCAs and 10:2 FTOH over 1-2 orders of magnitude, suggesting that the continues trapping of atm. particulates resulted in the accumulation of these compounds in bark. Overall, this study provides the first evidence that atm. particulate is an obvious source of C₈-C₁₂ PFCAs and 10:2 FTOH in tree bark. This result may further contribute to the application of tree bark as an indicator of certain PFASs in atm. particulate.

Per- and polyfluoroalkyl substances (PFASs) contamination in the Bohai Sea and its surrounding rivers has attracted considerable attention in recent years. However, few studies have been conducted regarding the distribution of PFASs in multiple environmental media and their distributions between the suspended particles and dissolved phases. In this study, surface water, surface sediment, and air samples were collected at the Bohai Sea to investigate the concentration and distribution of 39 targeted PFASs. Moreover, river water samples from 35 river estuaries were collected to estimate PFAS discharge fluxes to the Bohai Sea. The results showed that total ionic compound (∑ i-PFASs) concentrations ranged from 19.3 to 967 ng/L (mean 125 ± 152 ng/L) in the water and 0.70-4.13 ng/g dw (1.78 ± 0.76 ng/g) in surface sediment of the Bohai Sea, resp. In the estuaries, ∑ i-PFAS concentrations were ranged from 10.5 to 13500 ng/L (882 ± 2410 ng/L). In the air, ∑ PFAS (∑ i-PFASs + ∑ n-PFASs) concentrations ranged from 199 to 678 pg/m³ (462 ± 166 pg/m³). Perfluorooctanoic acid (PFOA) was the predominant compound in the seawater, sediment, and river water; in the air, 8:2 fluorotelomer alc. was predominant. Xiaoqing River discharged the largest ∑ i-PFAS flux to the Bohai Sea, which was estimated as 12,100 kg/y. Some alternatives, i.e., 6:2 fluorotelomer sulfonate acid (6:2 FTSA), hexafluoropropylene oxide dimer acid (HFPO-DA), and chlorinated 6:2 polyfluorinated ether sulfonic acid (Cl-6:2 PFESA), showed higher levels than or comparable concentrations to those of the C8 legacy PFASs in some sampling sites. The particle-derived distribution coefficient in seawater was higher than that in the river water. Using high resolution mass spectrometry, 29 nontarget emerging PFASs were found in 3 river water and 3 seawater samples. Further studies should be conducted to clarify the sources and ecotoxicol. effects of these emerging PFASs in the Bohai Sea area.

Zheng, Guomao;Salamova, Amina research published 《 Are Melamine and Its Derivatives the Alternatives for Per- and Polyfluoroalkyl Substance (PFAS) Fabric Treatments in Infant Clothes?》, the research content is summarized as follows. Per- and polyfluoroalkyl substances (PFAS) and melamine (MEL)-based compounds are used in textile finishing as grease, stain, and water repellents. Here, we investigated the occurrence of a large suite of PFAS and MEL compounds in 86 infant clothing items. The ∑MEL concentrations ranged from below the method detection limit to 250,000 ng/g with a median concentration of 78.2 ng/g, significantly higher (p < 0.05) than the ∑PFAS levels (1.22-203 ng/g; median 3.62 ng/g). MEL and its derivatives were most abundant in nylon clothes (median 32,800 ng/g), followed by organic cotton (median 6120 ng/g). In a simulated laundering experiment, the ∑MEL concentrations in clothing decreased on an average by ~60 and 90% when washed in cool (20°C) and warm (50°C) water, resp. This removal rate increased to 97% when the samples were washed with a detergent. The estimated daily intakes of MEL and PFAS through dermal absorption from nylon clothes were three orders of magnitude higher than those from the non-nylon clothes and decreased by more than half for washed clothes. Our findings demonstrate that MEL-based compounds are abundant in infant clothing and suggest that this group of compounds could be used as potential PFAS replacements in textile finishing.

Zhang, Hongna;Wen, Bei;Huang, Honglin;Wang, Sen;Cai, Zongwei;Zhang, Shuzhen research published 《 Biotransformation of 6:2 fluorotelomer alcohol by the whole soybean (Glycine max L. Merrill) seedlings》, the research content is summarized as follows. Fluorotelomer alcs. (FTOHs) are important precursors of perfluorocarboxylic acids (PFCAs) in the environment and biota. With the growing application of 6:2 FTOH [F(CF₂)₆CH₂CH₂OH] in product formulation, it is becoming increasingly urgent to investigate its biol. fates in different species. In this study, biotransformation of 6:2 FTOH by young soybean plants (Glycine max L. Merrill) were investigated using hydroponic experiments During the 144 h-exposure, 6:2 FTCA [F(CF₂)₆CH₂COOH], 6:2 FTUCA [F(CF₂)₅CF=CHCOOH], 5:3 FTUCA [F(CF₂)₅CH=CHCOOH], 5:3 FTCA [F(CF₂)₅CH₂CH₂COOH], PFHxA [F(CF₂)₅COOH] and PFPeA [F(CF₂)₄COOH] were phase I metabolites in soybean. At the end of exposure, 5:3 FTCA (5.08 mol%), PFHxA (2.34 mol%) and PFPeA (0.58 mol%) were three main metabolites in soybean-solution system. 5:3 FTCA was predominant in soybean roots and stems, while PFHxA was the most abundant product in leaves. PFBA [F(CF₂)₃COOH] and 4:3 FTCA [F(CF₂)₄CH₂CH₂COOH] detected in the hydroponic solution most-likely came from the transformation of 5:3 FTCA by root-associated microbes. Moreover, phase II metabolites of 6:2 FTOH were identified and monitored in soybean tissues. Alc. dehydrogenase, aldehyde dehydrogenase and glutathione S-transferase were found to participate in 6:2 FTOH metabolism Based on the phase I and phase II metabolism of 6:2 FTOH in soybean, this study for the first time provides evidences for the transformation pathways of 6:2 FTOH in plants.

Zhang, Long;Kong, Qinggang;Kong, Fanxin;Liu, Taolin;Qian, Haiyan research published 《 Synthesis and surface properties of novel fluorinated polyurethane base on F-containing chain extender》, the research content is summarized as follows. A novel fluorinated chain extender, (1-(ethyl(2-hydroxyethyl)amino)-3- ((3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)oxy)propan-2-ol) (FPO), was synthesized and characterized by NMR, Fourier transform IR (FTIR), and elemental anal. Poly (ether urethane)s containing various amounts of the chain extender with fluorinated side chains (FPUs) were prepared by isophorone diisocyanate (IPDI), polytetra-methylene-ether-glycol (PTMG), 3-aminopropyltriethoxysilane (KH-550), and 1,4-butanediol (BDO). Films of FPUs were investigated by water absorption, contact angle, pencil hardness, adhesive force, and thermal anal. Coating FPUs on micro-nano concave-convex structure plate realizes superhydrophobic performance. Scanning electron microscope (SEM) and at. force microscopy (AFM) demonstrated that there is a lot of irregular concave-convex structure, which forms a typical air cushion model. XPS anal. showed that surface fluorine content is 165% more than that of film average fluorine content. The superhydrophobic plate with 10% or higher F-containing FPUs coating is of outstanding chem. corrosion resistance, excellent solvent resistance, and wear resistance.
