| 초록 | A comb-like copolymer consisting of a poly(vinylidene fluoride-co-chlorotrifluoroethylene) backbone and poly(hydroxy ethyl acrylate) side chains, i.e. P(VDF-co-CTFE)-g-PHEA, was synthesized through ATRP using CTFE units as a macroinitiator. Successful synthesis and a microphase-separated structure of the copolymer were confirmed by proton nuclear magnetic resonance (1H-NMR), FT-IR spectroscopy, and TEM. This comb-like polymer was crosslinked with 4,5-imidazole dicarboxylic acid (IDA) via the esterification of the OH groups of PHEA and the COOH groups of IDA. Upon doping with phosphoric acid (H3PO4) to form imidazole-H3PO4 complexes, the proton conductivity of the membranes continuously increased with increasing H3PO4 content. A maximum proton conductivity of 0.015 S/cm was achieved at 120 oC under anhydrous conditions.
