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.
