Conductivity, Dielectric And Modulus Studies Of Methylcellulose-NH4TF Polymer Electrolyte

Abstract

Solid biopolymer electrolyte based on methylcellulose (MC) were prepared with different weight percentage of ammonium triflate (NH4TF) salt via solution casting technique. The film was characterized by impedance spectroscopy to measure its ionic conductivity. Samples with 45% of NH₄TF exhibit the highest conductivity of 1.14 x 10^-4 S cm^-1at ambient. Dielectric data were analysed using complex permittivity and complex electrical modulus for the sample with highest conductivity. Dielectric data proved that the increase in conductivity is mainly due to the increase in number of charge carriers.
