Abstract
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 LiClO4). 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. � (2013) Trans Tech Publications, Switzerland.
