▎ 摘  要

NOVELTY - PVC nanocomposite with graphene (GN) is obtained by dispersing nanofiller in PVC suspension solution in tetrahydrofuran containing 3-15 wt.% PVC, 0.05-1.5 wt.% Curcuma longa rhizome extract, and 0.01-5 wt.% GN based on the weight of the dissolved polymer, using ultrasound, evaporating solvent using known methods, and obtaining PVC/GN nanocomposite in the form of a film. USE - The method is useful for obtaining PVC nanocomposite with graphene (GN). ADVANTAGE - The method provides for the production of PVC nanocomposites with GN with a very good dispersion of nanofillers in the polymer matrix. In addition, the extended stability time of GN dispersion in a PVC solution enables its storage and transport between individual technological nodes for the production of PVC/GN nanocomposites.
