Investigations on the effect of Si0₂ on plasticized mg30 polymer electrolytes / Siti Nor Hafiza Mohd Yusoff

The potential of 30% poly (methyl methacrylate) grafted natural rubber (MG30) as a polymer host, zinc chloride (ZnCfe) as a salt, ethylene carbonate (EC) as a plasticizer and silicon dioxide (Si02) as a inorganic filler were prepared to form the flat, thin and flexible films by solution casting technique. The highest conductivity value of solid polymer electrolytes which is MG30 added with salt is 2.389 x 10"5 S/cm with 60 wt.% of Si02 at room temperature. The polymer host which is MG30 was added with salt, plasticizer and nanofiller to form composite polymer electrolyte. The ionic conductivity was investigated by using impedance spectroscopy. The highest conductivity of 1.072 x 10"3 S/cm was obtained from 20 wt.% of Si02 nanofiller at room temperature.
