Polyvinyl alcohol-Na montmorillonite nanocomposites films obtained by solution intercalation

Polyvinyl alcohol (PVA) is a well known film forming polymer used in several bioapplications. His advantages related to the physico-chemical properties are induced both by a certain orientation of macromolecular chains and an advanced level of biodegradability. The main objectives of this study were the obtaining of polyvinyl alcohol nanocomposite with a natural unmodified layered silicate, the layered silicate structure investigation by XRD before and after polymer intercalation and the investigation of the thermal behavior of the PVA-NaMMT nanocomposites.
