lmprovement of Proton Transport via Preparation Composite Membrane of SPSF/Nafion

Abstract

:;PSFlNafioo proton exchange composite membrane has been prepared by phase inversion technique. Here, the matrix of SPSF was mpregnated with a 5% Nafion solution in various time of evaporation. The presence of Nation in the matrix is presumed to affect in structure formation of membrane, consequently affect on physicochemical and proton transport properties. Characterization of he composite membrane was performed include water uptake, ionic exchange capacity, membrane morphology and proton .onductivity. As the result, water uptake and hydration capacity decrease with increasing evaporation time up to 10 min, the further waporation time increase significantly. The proton conductivity of the composite membrane increase LIpto 10 min the further evaporation times tend to decrease. Nevertheless, compared with Sf'Sf membrane, the composite membrane shows improvement he proton conductivity.
