摘要：

Copolymers of acid phosphoxyethyl methacrylate (PHM) and 2,2,2-trifluoroethylacrylate (TFEA) were synthesized in order to construct hydrophilic and hydrophobic domains as well as Nafion(R) membrane. Thermal decomposition temperatures of PHM-TFEA copolymers were about 250 degreesC, which showed sufficient thermal stability for polymer electrolyte fuel cells (PEFC). Water uptake of these copolymers was higher than that of Nafion 115 under low relative humidity, and proton conductivity of these polymers exhibited about 10(-3) S cm(-1) under 90% relative humidity at 80 degreesC.
