    • Abstract


      The lithium ion conducting copolymer electrolytes based on poly(vinylidene chloride-co-acrylonitrileco- methyl methacrylate) P(VdCl-co-AN-co-MMA)-lithium per chlorate (LiClO4) (P(VdCl-co-AN-co-MMA): LiClO4) and poly(vinylidene chloride-co-acrylonitrile-co-methyl methacrylate)P(VdCl-co-AN-co-MMA)-lithium per chlorate (LiClO4)-ethylene carbonate (EC) (P(VdCl-co-AN-co-MMA):LiClO4:EC) of different compositions were prepared by solution-casting technique. Structural and surface morphological characterizations were studied by X-ray diffraction analysis and scanning electron microscopy measurements, respectively. Thermal and conductivity behaviour of copolymer–salt and copolymer–salt–plasticizer complexes were studied by employing differential scanning calorimetry and AC impedance measurements, respectively. The highest bulk conductivity was found to be 1.94 × 10-4 S cm-1 at 303 K for the plasticized sample. The dielectric behaviour and relaxation parameters of the samples have been presented and discussed.
