Role of Salt Concentration Lithium Perchlorate on ionic Conductivity and Structural of (Glycidyl Methacrylate -co-Ethyl Methacrylate) (70/30) Based on a solid polymer electrolyte

摘要

A new solid polymer electrolytes (SPE) comprising copolymer of poly(glycidyl methacrylate, GMA) and (ethyl methacrylate, EMA) as polymer host and LiClO4 as dopant was prepared by solution-casting technique. The copolymer was prepared by photopolymerization method and was characterized using NMR. The SPEs were characterized using electrochemical impedance spectroscopy (EIS), fourier transforms infrared (FTIR) and X-ray diffraction (XRD). The highest conductivity achieved was 4.0x10~(-4) at 373K with highest conductivity at room temperature (2.7x10~(-5) S cm~(-1) at 30 wt. % of LiClO_4). The active coordination site for the cation (Li~+), three electrons donating functional carbonyl, ether and epoxy group of the GMA-co-EMA host have been evaluated base on their properties that were recorded in (FTIR). The structural analysis showed reduction in copolymer crystallinity phases at its highest conductivity.
