摘要

Nano-sized MgO particles were synthesized through sol-gel method and dispersed as filler in PVC-PEG ma7 trix with lithium perchlorate (LiCIO4) as dopant salt. The content of MgO particles in the electrolyte was var:ed to study its influence on the ionic conductivity of the'membranes. The electrolyte films were subjected to XRD, AC iinpedance analysis. The 'analysis reveals the 'strong influence' of MgO particles on tlie conductivity profile; The conductivity of MgO doped electrolyte membranes exhibits two lmaxima one occurring at.1 wMand other at 6, wt% of filler. The film with composition (PVC-PEG-PC-LiClO4-MgO) (19-15-50-10-6) exhibits higher conductivity of 6.034 x 10(-6) S/cm at room temperature. Ten times enhancement in the conduc,tivity value was observed. The thermal stability of the membrane 'was estimated through TGA analysis. The SEM analysis shows the porosity and connectivity of the pores was determined by The MgO content.
