Abstract
Polypyrrole conducting polymers have become significant in different biomedical applications, but unfortunately, they are insoluble with poor mechanical properties. A natural soluble polymer (Chitosan) can be used to improve such properties. Chitosan/polypyrrole composites were synthesized by dispersing the different doped amounts of polypyrrole into the chitosan matrix. The physical properties of the synthesized composite films were investigated using different techniques. The results obtained from FTIR, XRD show the electrostatic interaction between chitosan and polypyrrole. UV/Vis analysis implies that the optical band gap of composite films decreases with increasing polypyrrole concentration, which can be assumed to increase the electrical conduction in the composite films.
