Poly (Methyl Methacrylate)-Salicylic Acid-Oleic Acid Plasticized Gel Electrolyte System: Electrical and Ionic Transport Study
M.I.N. Isa

Abstract:
The effect of temperature on electrical and ionic transport properties of PMMA-SA-OA Gel Polymer Electrolyte (GPE) system have been studied in this work. The GPEs have been prepared via solution casting technique and investigated in the temperature ranges from ambient to 368 K. Electrochemical Impedance Spectroscopy technique has been employed to determine the behaviors. The conductivity of the GPE is 8.65x10-4 S cm-1 at ambient temperature and increases to 1.93x10-2 S cm-1 at 368 K. The GPEs show non-Debye type of materials where the regression value obtained from the log conductivity versus reciprocal temperature is close to unity (R2~1). The complex permittivity, electrical modulus and tangent loss study shows the plurality of relaxation process, thus confirm the Grouttus’ mechanism process occurred in the GPE system. The activation energy calculated decreases with temperature. The conductivity shows significant influenced of the ionic transport properties i.e. number of ions (n), mobility of ions (μ) and diffusion coefficient of ions (D).
