Abstract
Copolymer electrolytes based on 5-(methacrylamido)tetrazole (MTet) and vinyl phosphonic acid (VPA) are prepared. The obtained copolymers are analyzed by FTIR, H-1 NMR, C-13 NMR, and P-31 NMR spectroscopy, thermogravimetric analysis (TGA), differantial scanning calorimetry (DSC), energy dispersive X-ray spectrometry (EDS), elemental analysis (EA), cyclic voltammetry (CV), and impedance spectroscopy. The morphology of the copolymers is characterized by X-ray diffraction (XRD), atomic force microscopy (AFM) and scanning electron microscopy (SEM). The highest proton conductivity is obtained as 0.01 S/cm at 150 degrees C and in anhydrous conditions.
