Investigations on PVdF- HFP - PEMA polymer blend electrolytes doped with different lithium salts
[摘要] Plasticized polymer blend electrolytes were prepared by incorporating poly (vinylidenefluoride-co-hexafluoropropylene)(PVdF-HFP) and poly(ethylmethacrylate) (PEMA) complexed with plasticizer (PC) and different lithium salts such as LiClO4, LiBF4, LiCF3SO3and LiN (CF3SO2)2) using solution-casting technique. X-ray diffraction and Fourier transform infra-red techniques confirms the structural characters and complex formation of the polymer electrolytes respectively. AC impedance analysis was carried out for all the samples in the range303-373K. The results suggest that among the various lithium salts, LiN (CF3SO2)2) based electrolytes exhibited the highest ionic conductivity (3.17 × 10-3Scm-1).
