Effect of Adipic Acid Composition on Structural and Conductivity Solid Biopolymer Electrolytes Based on Carboxy Methylcellulose Studies

Solid biopolymer electrolytes (SBEs) based on carboxy methylcellulose (CMC) has been prepared by doping different concentration of Adipic acid (AA) via solution casting technique. Fourier Transform Infrared spectroscopy was used to study the interaction between the host and ionic dopant. New peaks were observed at at 1714 and 1261 cm-1at AA-5. It also can observe that 5 peaks intensity have become decrease. XRD analysis was shown the CMC-AA was the amorphous solution.The highest ionic conductivity achieved at room temperature is 6.12 x 10-7 S cm-1 for CMC incorporated with 5 wt. % AA. In addition, the temperature dependence of the SBEs exhibit Arrhenius behavior. That the activation energy of relaxation is lower than the activation energy of conduction implies that the charge carrier has to overcome the higher energy barrier during conducting.
