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).

The XRD results confirmed that the property improvements were related to the MMT exfoliation and good interaction between PVA/chitosan blend and MMT. Mechanical properties of the films were influenced significantly by the nano-clay particles. [Hamid Mahdavi , Hamid Mirzadeh , Mohammad Jalal Zohuriaan-Mehr , Fateme Talebnezhad .
