摘要
Poly(bis(phenoxy)phosphazene)(SPBPP)/phosphotungsticacid(PWA)/silicacompositemembranesforfuelcellswereprepared.ThecompositemembraneswerecharacterizedbyusingFTIR,TGAandSEMtechniquies.IncorporationofPWAparticlesandsilicaparticlesintotheSPBPPpolymermatrixandaspecificinteractionbetweenthemwereconfirmedbyFTIRspectra.TGAresultsshowedthatthecompositemembraneshadhighthermalstability.HomogeneousdistributionofPWAandsilicaparticleswithintheSPBPPmatrixwasverifiedbySEMmicrographs.Thedopedmembranesshowedincreasedwateruptakeandprotonconductivity.
