摘要: Abstract Proton conducting polymer membranes have become crucial due their applications in fuel cells as source of clean energy. In this work, we synthesized poly(glycidyl methacrylate) (PGMA) by conventional free radical polymerization GMA using azobisisobutyronitrile (AIBN) initiator. PGMA was modified with 5-aminotetrazole ring opening the epoxide group. The composition studied elemental analysis (EA) and structures were characterized FT-IR solid 13C NMR spectra. Thermogravimetry (TG) differential scanning calorimetry (DSC) employed to examine thermal stability homogeneity materials, respectively. Polymers doped H3PO4 at several stoichometric ratios. effect doping on proton conductivity via impedance spectroscopy. Maximum acid-doped PGMA-aminotetrazole found be 0.01 S/cm 150 °C anhydrous state.
