PVC + (NH4)HS04 + SiOz (lO^m) polymer electrolytes and its electrical properties / Nurhashidah Anuar

Polymer electrolytes composed of PVC (polyvinyl chloride) as a host polymer, (NH4)HS04 as a salt and SiO2(10/im) as a filler will be prepared by solution cast technique using tetrahydrofuran (THF) as a solvent. The conductivity measurements of the samples were carried out using HIOKI-LCR Hi-Tester and are analyzed using impedance spectroscopy (IS). The sample with highest conductivity was recorded for 60 wt % PVC - 40 wt % (NH4)HS04 with value of 1.32E-08 Son"1. The effects of addition of micro sized SiC>2 adder on the conductivity of the highest conducting any polymer electrolyte was investigated. The highest conductivity was obtained for 92 wt % PVC - (NH4)HS04- 8 wt % Si02 with value of 3.23E-05 Son"1 which is an increase of 3.23E-05 orders of magnitude compared to the filler-free sample.
