Abstract:

In the present study, proton conducting biopolymer electrolyte systems based on corn starch and NH4SCN salt were prepared using solution casting method. The sample with 30 wt.% NH4SCN exhibited the highest ionic conductivity of 5.54 x 10-3 S cm-1 at room temperature. Temperature-dependence ionic conductivity relationship obeys Arrhenius model and minimum activation energy of 0.28 eV was obtained for the highest conducting composition.
