Natural Polymer Electrolyte System Based on Sago: Structural and Transport Behavior Characteristics
The development of natural polymer electrolytes (NPEs) based on sago was accomplished in this work by incorporating NH4Br via the solution-casting method. The polymer-salt complex formation and ionic conduction of the NPEs were analyzed by FT-IR and impedance measurement
studies. The highest ionic conductivity for the sago-based NPE system at room temperature is 6.90 × 10−9 Scm−1. In addition, the temperature-dependent ionic conductivity of the NPE system obeys the Arrhenius rule. It was shown that the conducting
species in this present work is predominantly due to proton (H+), which was confirmed via FT-IR analysis.
