Abstract:

Abstract: Gel polymer electrolytes with ionic liquid [BMIM]Cl-ZnCl2 and aprotic solvents in vinyl monomers matrix MA、MMA、HEMA were prepared and studied.The polymer electrolytes were formed by in situ free radical polymerization.Structure and properities of the product were studied using FTIR、AC、TG.The interactions and structure changes of the composites were investigated by FTIR. The combination of a Lewis acid c ionic liquid, [BMIM]Cl-ZnCl2 with aprotic solvents,[BMIM]Cl-ZnCl2,PCand DMC strongly increases the ionic conductivity in comparison with the neat ionic liquid.，which showed highly ionic conductivity up to2.83×10−3 S/cm at room temperatur. And the activation energies of ions were calculated according to VTF equation.Gel polymer electrolytes exhibited high decomposition temperatures above 275 ℃.

Key words: vinyl monomer,ionic liquid,aprotic solvent,ionic conductivity,thermal stability,in situ radical polymerization
