Abstract

Ionic liquids containing the 1 -butyl- 1-methylpyrrolidinium ([C ₄mPyrr]+) cation and bis(trifluoromethanesulfonyl)imide ([NTf ₂]") anion have been synthesized and incorporated in 49% PMMA grafted natural rubber together with lithium salts to obtain solid polymer electrolytes (SPEs). The resultant SPEs obtained, are freestanding, flexible film and translucent and show conductivity over a wide range of 10 ^-3-10 ^-5 S cm ^-1. Polymer electrolytes containing 80% of (MG49:LiCF ₃S0 ₃) and 20% of [C ₄mPyrr] [NTf ₂] showed the highest conductivity of 2.11 x 10 ^-3 S cm ^-1 at room temperature. The examination of the ion- polymer interactions and ionic conductivity are discussed and investigated by FT-IR and Electrochemical Impedance Spectroscopy (EIS) respectively.
