Abstract

Polymeric hydrogels are a new class of biomaterials that have recently attracted a lot of attention for application in medical and pharmaceutical areas. They possess the most of desirable characteristics of an ideal dressing, but they have low mechanical strength to be used in under-tension positions of the body.

Abstract

The present attempt is intended to prepare nano-composites of polyvinyl alcohol (PVA) blended chitosan and nano-clay montmorillonite (MMT) particles. PVA/chitosan films containing nano-clays particles were prepared by coating method and their physical and mechanical properties were studied by tensile tests, X-ray diffraction (XRD) and scanning electron microscopy (SEM).
