摘要: This work reports the preparation and characterization of a new anhydrous proton conducting membrane based on poly(vinyl alcohol) (PVA), sulfosuccinic acid (SSA), 5-aminotetrazole (ATet) at various stoichiometric ratios. The conductivities membranes were investigated as function ATet composition, SSA temperature. New characterized by infrared spectra, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), dynamic mechanical (DMA), methanol permeability, impedance measurements for conductivity. TGA showed that samples thermally stable up to 150°C. DSC results illustrated homogeneity materials. Mechanical storage modulus PVA–SSA–ATet blend polymer decreased with increasing content. higher tetrazole content, or doping level presented PVA–SSA–ATet4 can exhibit an conductivity 1.7 × 10−3 S/cm 130°C increased temperature level.
