Electrokinetic properties of biodegradable conducting polyaniline-graft-chitosan copolymer in aqueous and non-aqueous media

- PAni-g-CS was synthesized by radicalic polymerization.
- PAni-g-CS was characterized by 1H NMR, UV-vis, TGA and SEM techniques.
- ζ-Potential of PAni shifted to more positive regions after grating with CS.
- ζ-Potentials were found to be in colloidally stable range in both aqueous and non-aqueous SO media.
- PAni-g-CS showed an improved antibacterial activity against Escherichia coli.
