Abstract

In this study, 30% methyl grafted natural rubber (MG-30) containing fixed amount of lithium trifluoromethanesulfonate (LiCF₃SO₃) or LiTf salt and ethylene carbonate, EC and different concentration of Si0₂ nanofiller were prepared using the solution cast technique. Impedance spectroscopy technique was used to determine the electrical conductivity of the samples. The optimum electrical conductivity obtained was 2.36x10⁻⁴ S cm⁻¹ with the composition of 35wt% MG-30:65wt% LiTf:65wt% EC:1.5wt% Si02. The conductivity was calculated using the bulk resistance value what was obtained from the complex impedance plot in the frequency range from 100Hz to 1MHz. The ionic transference number obtained from the Wagner's polarization method is 0.986 which indicates the samples are ionic conductors.
