Abstract :

The proton conducting tri block copolymer electrolytes based on Poly(vinylidene chloride–co–acrylonitrileco–methyl methacrylate)(P(VdCl–co–AN–co–MMA)–Ammonium thio cyanate (NH4 SCN) (P(VdCl–co–AN–coMMA):NH4SCN) and Poly(vinylidene chloride–co–acrylonitrile–co–methyl methacrylate)P(VDCl–co–AN–co–MMA)–Ammonium thio cyanate (NH4SCN)–Ethylene Carbonate (EC) (P(VdCl–co–AN–co–MMA):NH4 SCN:EC of different compositions were prepared by solution casting technique. Structural and surface morphological characterizations were studied by X–ray diffraction (XRD) analysis and Scanning Electron Microscopy (SEM) measurements respectively. The conductivity behaviors of copolymer–salt and copolymer–salt–plasticizer complexes were studied by employing ac impedance measurements. The highest bulk conductivity was found to be 1.32 x 10–3 S cm–1 at 303 K for the plasticized sample. The conductance, dielectric behavior and relaxation parameters of the samples have been presented and discussed
