Nafion 117 membranes were modified by in situ chemical polymerization of 3,4-ethylenedioxythiophene using H 2 O 2 as oxidant for direct methanol fuel cell application. Methanol permeability and proton conductivity of the poly(3,4-ethylenedioxythiophene)-modified Nafion membranes as a function of temperature were investigated. An Arrhenius-type dependency of methanol permeability and...
A new kind of inorganic–organic composite membranes based on sulfonated polyethersulfone Cardo (SPES-C) with embedded phosphotungstic acid (PWA) was prepared. The composite membranes were characterized by using FT-IR, XRD, TGA and SEM techniques. FT-IR and XRD measurements confirmed the presence of PWA particles into the polymer matrix. FT-IR spectra indicated the existence of a specific interaction...
