▎ 摘 要
The goal of the paper was to investigate the influence of graphene (GN) on properties and structure of suspensive poly(vinyl chloride) (PVC). PVC/GN nanocomposites were obtained by the solvent evaporation method, and their structures were evaluated using optical microscopy, SEM, FT-IR, XRD and Raman spectroscopy methods. Thermal properties of the obtained materials were studied by TGA. Electrical properties and swelling behaviour were also determined. The microscopic observations confirm a uniform distribution of graphene in the PVC matrix. The investigations carried out indicated an effect of graphene on a decrease in resistivity to a value which enabled to include the PVC/GN nanocomposites into anti-static materials group. On the basis of swelling studies, it has been found that the PVC/GN nanocomposites have a higher chemical resistance against acetone while compared to pure poly(vinyl chloride). The properties of the obtained materials depend significantly on content and dispersion level of graphene in the PVC matrix. An impact of GN on the acceleration of the PVC degradation process was found.
