Chitin and Chitosan Based PVC Composites and Nanocomposites

Poly(vinyl chloride) is a thermoplastic material quite versatile and with wide application in society. Still, the application possibilities can be expanded through composite material with PVC as a matrix associated with biopolymers. These developments allow for improving chemical, thermal and mechanical properties and contributing to more environmentally friendly technologies. Among the biopolymers, chitin and chitosan stand out given their natural occurrence, abundance, biodegradability, biocompatibility, adsorption capacity, antimicrobial action, and easy modification. This chapter will be addressed some of the PVC-based composites containing chitosan and possible applications of these materials.
