Description
Summary:Composite films were prepared from solutions of cellulose-polyacrylonitrile blends in a mixed solvent, 1-butyl-3-methylimidazolium chloride-dimethylformamide. The rheological properties of the solutions were studied. The structural organization and heat resistance of the composite films were examined by X-ray diffraction and thermal gravimetric analysis. Introduction of cellulose into the polyacrylonitrile matrix decreases the temperature of polyacrylonitrile cyclization onset and enhances the heat resistance of the composite films.
