The development of biobased polymer originated from vegetable oil has become one of the areas of interest in research field. Jatropha oil-based polyurethane acrylate has been prepared by three stages of reaction: epoxidation, hydroxylation, followed by introducing acrylate group in urethanation process. A new development of polyurethane acrylate gel polymer electrolyte was achieved by doping with 5–25 wt % LiClO4 and curing by UV irradiation method. The highest ionic conductivity was achieved with 15 wt % LiClO4 salt content, which is 8.955 × 10–5 S cm–1 at room temperature. The achievement of higher conductivity in gel polymer electrolyte was comparable in terms of salt content and without plasticizing effects. Polyurethane acrylate gel electrolyte was analyzed by Fourier transform infrared spectroscopy (FTIR), which recorded the presence of hydroxyl and amine groups in polymer and gel electrolyte. NMR analysis confirmed this finding. Thermal stability of gel electrolyte was measured by thermal gravimetr...
