Abstract

A series of electrically conductive zwitterion hybrid materials were facilely synthesized with anionic acacia gum (AG) and cationic HCl doped polyaniline WAND through radical copolymerization method. A representative acacia gum-polyaniline hybrid (AG-PANI) was characterized using UV-vis, FTIR, (1)H NMR, and SEM. HCl doped AG-PANI possesses zwitterion character due to the presence of NH(3)(+) on PANI and -COO(-) of AG. The cyclic voltammogram of AG-PANI showed three anodic peaks at 0.20 V, 0.58 V, and 0.64 V along with two cathodic peaks at 0.50 V and 0.40 V with large capacitive background currents. AG-PANI exhibited electrical conductivity that was found dependent on the ratio of aniline to AG, temperature, and pH. Its electrical conductivity versus temperature plot indicated Mott's nearest-neighbor hopping mechanism at the temperature range 83-323 K. The hybridization of AG and PANI yielded eco-friendly advanced functional materials for technological applications.
