ABSTRACT
In this work, different amounts of sodium bisulfite, NaHSO3 (5wt.% to
40wt.%), were dissolved in a corn starch polymer host to synthesize solid
polymer electrolyte (SPE) using a solution casting technique. Then, the films
prepared were characterised using non-destructive electrical impedance
spectroscopy to determine SPE films' conductivity and electrical transport
properties. The highest conductivity of the sample at ambient temperature
was recorded at 15wt. % of NaHSO3 with a value of 2.22 × 10-4 Scm-1.
Moreover, the ion transport parameters at room temperature are found to
be 2.41 × 10-7 cm2s-1, 9.39 × 10-6 cm2V-1s-1, 1.70 × 1019 cm-3 for D, μ and
n, respectively. The conductivity of the samples was found dependent on
diffusion coefficient, D and mobility, μ of ions.
