Chitosan Combined with Conducting Polymers for Novel Functionality: Antioxidant and Antibacterial Activity


Article Preview

Chitosan as a natural biopolymer has applicable functionality for wound healing due to the biocompatible and antibacterial properties. Here we investigate what combined biomimetic functionality can be obtained by forming composites of chitosan and conducting polymers such as polypyrrole (PPy) or poly (3,4-ethylenedioythiophene) (PEDOT). Chemical polymerization shows direct interaction between the chitosan matrix and PPy; such materials can be dissolved as stable suspensions, coated (printed or spin coated) on fabrics or fibers with antioxidant properties of renewable activity. PEDOT and chitosan composites have shown antibacterial properties against staphylococcus aureus. The novel biocompatible chitosan conducting polymer composites will give new direction for obtaining smart materials with diverse functionality, applicable as sensors, food packaging or ion-selective membranes.
