In this research, two solid bio-polymer electrolyte (SBE) systems of an unplasticized carboxyl methylcellulose doped with oleic acid (CMC–OA) and a similar system plasticized with Glycerol (CMC–OA–Gly) have been successfully prepared by solution casting technique. Both SBEs system were free-standing, transparent with no phase separation films. Fourier Transform Infrared (FTIR) analysis reveals that complexations have occurred between CMC and OA at 2850 cm-1, 2920 cm-1 and 1597 cm-1. No significant complexation was observed with the addition of Gly, hence, Gly has acted as a new pathway which helped in the hopping of H+ to other coordinating sites of carboxylate anion (COO¯) moiety in CMC.
