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:LiCF3S03) and 20% of [C4mPyrr] [NTf2] 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.Room temperature ionic liquid/solid polymer electrolyte/PMMA grafted natural rubberjournal article10.22452/mjs.vol28no2.102-s2.0-69549122343
