Abstract In this work, a novel polyether grafted acrylic resin-based gel polymer electrolyte was prepared by UV curing with methoxy polyethylene glycol acrylate (PEGMEA) and polyurethane acrylic resin (PUA) as monomers and ionic liquid 1-butyl-3-methylimidazoliumbis (BMimTFSI) as additives. The gel polymer electrolyte was characterized by FTIR, TG, UV-Vis, and cyclic voltammetry. The results show that this kind of gel polymer electrolyte not only has excellent ionic conductivity but also has the advantages of high thermal stability, easy encapsulation, and non-lea-kage. Among them, the gel polymer electrolyte with BMimTFSI content of 59.5% and PUA/PEGMEA ratio of 4.96∶2.96 has the best comprehensive performance, the visible light transmittance of more than 90%, the thermal decomposition temperature of 300 ℃, and ionic conductivity of 2.17×10-5 S/cm at 30 ℃. Electrochromic devices based on this kind of gel polymer electrolyte show excellent performance. After 36 000 s, it still maintains color switching which is from a blue state to a transparent state, and the visible light transmittance contrast of colored and faded states is still as high as 48%. The electrolyte is soft and has good thermal stability. It can be applied to electrochromic devices.
