Abstract

Polyvinyl alcohol (PVA) is a nontoxic biodegradable, thermoplastic polymer with excellent thermo-mechanical properties with good reinforcing material property have gained interest in many applications in different fields especially biomedical, tissue engineering etc., PVA based Novel materials are essential for next generation bio-related applications. This chapter begins with a briefing about PVA emphasizing advantages of biocomposites and bionanocomposites describe appraise of a type of PVA based biocomposites and bionanocomposites and their suitability for biomedical and biomaterial applications. It then enumerate their suitability for prospects biomedical and bio-engineering applications. These ingenious materials are capable of function as biodegradable films, for membrane separation, for tissue engineering, for food packaging, for wound healing and dressing, hydro gels formation, gels formation, etc.. Nonetheless, core technologies of composite fabrication, high water absorption, system design, poor mechanical properties are perilous concerns connected with PVA based biocomposites and bionanocomposites.
