The article was titled 《Effects of Anion and Cross-Linker on the Surface Hydrophilicity and Selective Solvent-Induced Swelling of Poly(ionic liquid) Elastomers》, and you may find the article in ACS Applied Polymer Materials.SDS of cas: 627-18-9 The information in the text is summarized as follows:
Poly(ionic liquid)s (PILs) have attracted great attention because they preserve conventional characteristics of polymers while having special features of ionic liquids, such as good ionic conductivity and excellent electrochem. and thermal stability. The solvent absorption behaviors and solvent-induced responsiveness of PIL elastomers, however, have been less investigated. In this work, we prepare two PILs, poly[C3mim-MA][Br] and poly[C3mim-MA][TFSI], and examine their surface hydrophilicities and solvent-induced responsiveness. Ionic liquid monomers are synthesized and then polymerized with initiators and crosslinkers via free radical polymerization, forming PIL elastomers. The anions in the monomers can be replaced using an ion exchange process to prepare PIL elastomers with different anions. The surface properties, swelling behaviors, and solvent responsiveness of the PIL elastomer films with different anions and crosslinker ratios are investigated. The surface hydrophilicities of the PIL films are characterized by water contact angle measurements; the poly[C3mim-MA][Br] elastomer films are more hydrophilic than the poly[C3mim-MA][TFSI] elastomer films. Due to the different hydrophilicities, the poly[C3mim-MA][Br] and poly[C3mim-MA][TFSI] elastomer films can be swollen selectively in water and acetone, resp. For both elastomers, the swelling degrees are higher at lower crosslinking densities, and the volume expansions can be up to 655%. Furthermore, we investigate the solvent-vapor-induced responsiveness of bilayer films of PIL elastomers and polyimide (PI) tapes. The bilayer films can be bent selectively by exposing them to water or acetone vapors, depending on the anions. After reading the article, we found that the author used 3-Bromopropan-1-ol(cas: 627-18-9SDS of cas: 627-18-9)
3-Bromopropan-1-ol(cas: 627-18-9) was used in the synthesis of fluorescent halide-sensitive quinolinium dyes and molten salt-polymers. Furthermore, it was used in the synthesis of chiral, quaternary prolines via cyclization of quaternary amino acids.SDS of cas: 627-18-9
