Abstract
This paper describes the preparation of a new type of water-soluble nanocomposite film from polyvinyl alcohol, Ni²-montmorillonite (Ni²-MMT), a defoaming agent, a levelling agent, and a plasticiser. Its thermal characteristics were studied by DSC, and the intermolecular interactions were measured by FTIR and XPS. The tensile strength and elongation at break were also measured. The microstructures were studied by XRD and AFM. FTIR and XPS spectra indicated that crosslinking had taken place between PVA and Ni²-MMT. XRD and AFM indicated that the PVA molecules had inserted themselves into the silicate layers of MMT, exfoliating them and dispersing them randomly into the PVA matrix. Compared to pure PVA film, the tensile strength of the films increased and the elongation at break decreased when the Ni²-MMT was added and the dissolution temperature of the film was also reduced. 23 refs.
