The article was titled 《Construction of ion conducting channels by embedding hydrophilic oligomers in piperidine functionalized poly(2,6-dimethyl-1,4-phenylene oxide) membranes》, and you may find the article in European Polymer Journal.COA of Formula: C8H19NO2 The information in the text is summarized as follows:
A suitable microphase separation morphol. has been demonstrated to be an efficient strategy to achieve high ionic conductivity with reasonable durability to anion exchange membranes (AEMs). Herein, hydrophilic oligomers of polyethylene glycols (PEGs) with different mol. weights were blended, sep., with poly(2,6-dimethyl-1,4-phenylene oxide) modified by 4,4-diethoxybutan-1-amine and 1-methylpiperidine (20PDM). The presence of hydrophilic PEGs facilitates the formation of the interconnected nano-channels in the AEMs for ion conduction according to the anal. results by both transmission electron microscopy (TEM) and small angle X-ray scattering (SAXS). The membrane containing 2 wt% PEGs with a mol. weight of 2 kDa reaches a hydroxide conductivity of 97.2 mS cm-1 at 80°C, which is 25 mS cm-1 higher than that the pristine 20PDM membrane possessing the same ion exchange capacity. A peak power d. of 328 mW cm-2 is attained at 60°C by the proposed membrane based single fuel cell fueling with humidified H2 and O2 with 0.1 MPa of back pressure. The chem. structure, water uptake and swelling as well as resistance to hot alkali solutions of the prepared membranes were investigated. In the experiment, the researchers used many compounds, for example, 4,4-Diethoxybutan-1-amine(cas: 6346-09-4COA of Formula: C8H19NO2)
4,4-Diethoxybutan-1-amine(cas: 6346-09-4) belongs to anime. Many important products require amines as part of their syntheses. Methylamine is utilized in the production of the analgesic meperidine (trade name Demerol) and the photographic developer Metol (trademark), and dimethylamine is used in the synthesis of the antihistamine diphenhydramine (trade name Benadryl), the solvent dimethylformamide (DMF), and the rocket propellant 1,1-dimethylhydrazine. The synthesis of the insect repellent N,N-diethyl-m-toluamide (DEET) incorporates diethylamine while that of the synthetic fibre Kevlar requires aromatic amines.COA of Formula: C8H19NO2
