摘要: Electrolytes of poly(trimethylene carbonate-co-e-caprolactone), poly(TMC-co-CL), and LiTFSI have been prepared characterised. The copolymers were analysed with GPC NMR, which showed that random high molecular weight desired compositions had obtained. electrolytes varied salt concentration examined TGA, DSC, FTIR impedance spectroscopy. highest ionic conductivities measured for the copolymer 60:40 ratio TMC:CL homopolymer poly(e-caprolactone), PCL, both 28 wt% LiTFSI. conductivity was to order 10−3 S cm−1 PCL electrolyte 10−4 at 50 °C.
