摘要
A novel comb-like copolymer electrolyte was designed by co-polymerizing of two macro-monomers: methoxy-poly (ethylene glycol) methacrylate (MPEGM) and hexadecal-poly (ethylene glycol) methacrylate (HPEGM), tris (methoxypolyethyleneglycol) aluminate ester (MPEG-Al ester), Li-salt (LiClO4). Performances of the polymer electrolytes were studied by FT-IR, DSC and alternating current (AC) impedance and so on. The results showed that P (MPEGM-HPEGM) had been formed and the motion of PEO chains had been improved. The polymer electrolytes possessed excellent thermal stability and electrochemical stability. And when the weight ratio of MPEGM to HPEGM to MPEG7-Al ester was 4:1:5, the maximum ionic conductivity value reached 0.43 × 10-3S/cm with n (Li+): n (EO) =1:20 at 30°C.
