The effect of different anions within the ionic liquid in the characteristics of solid polymer electrolytes (SPEs) based on P(VDF-TrFE) has been investigated. 1-ethyl-3-methylimidazolium acetate, [C(2)mim][OAc], 1ethyl- 3-methylimidazolium triflate, [C(2)mim][(CF3SO3)], 1ethyl- 3-methylimidazolium lactate, [C(2)mim][Lactate], 1-ethyl-3-methylimidazolium thiocyanate, [C(2)mim][SNC] and 1-ethyl-3-methylimidazolium hydrogen sulfate [C(2)mim][HSO4] have been used in SPE prepared by solvent casting. The polymer phase, thermal and electrochemical properties of the SPE have been determined. The thermal and electrical properties of the SPEs strongly depend on the selected IL, as determined by their different interactions with the polymer matrix. The room temperature ionic conductivity increases in the following way for the different anions: [SNC]>[CF3SO3)]> [HSO4]>[Lactate]>[OAc], which is mainly dependent on the viscosity of the ionic liquid.
