Abstract :

The lithium ion conducting tri block copolymer electrolytes based on Poly(vinylidene chloride–co–acrylonitrile–co–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 ):Dimethyl formamide (DMF) P(VdCl–co–AN–co–MMA):LiClO4 :DMF 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 interaction of Li+ ion with the copolymer and DMF has been studied by FTIR Analysis. 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 1.36 x 10–6 S cm–1 at 303 K for the plasticized sample. The conductance, modulus, dielectric behavior and relaxation parameters of the samples have also been presented and discussed.
