Improvement of proton transport via preparation composite membrane of SPSF/Nafion
MetadataShow full item record
SPSF/Nafion proton exchange composite membrane have been prepared by phase inversion technique. Here, the matrix of SPSF was impregnated with a 5% Nafion solution in various time evaporation. The presence of Nafion in the matrix is hypotheses to affect on structure formation of membrane, consequently affect on physicochemical and proton transport properties. Characterisation of the composite membrane was performed include water uptake, ionic exchange capacity, membrane morphology and proton conductivity. As the result, Water uptake and hydration capacity decrease with increasing evaporation time up to 10 minutes, the further evaporation time increase significantly. The proton conductivity of the composite membrane increase up to 10 minutes the further evaporation times tend to decrease. Nevertheless, Compared with SPSF membrane, the composite membrane shows improvement the proton conductivity.
