摘要

Abstract

Poly(bis(phenoxy)phosphazene) (SPBPP)/phosphotungstic acid (PWA)/silica composite membranes for fuel cells were prepared. The composite membranes were characterized by using FTIR

TGA and SEM techniquies. Incorporation of PWA particles and silica particles into the SPBPP polymer matrix and a specific interaction between them were confirmed by FTIR spectra. TGA results showed that the composite membranes had high thermal stability. Homogeneous distribution of PWA and silica particles within the SPBPP matrix was verified by SEM micrographs. The doped membranes showed increased water uptake and proton conductivity.
