The possibility of obtaining stable dispersions of carbon materials in organic solvents (benzene, toluene) and solutions of HRSR polydimethylsiloxane rubber with methods of mechanical and ultrasonic dispersion was studied. Stable uniform dispersion was received in solution of polydimethylsiloxane rubber using submersible ultrasonic disperser. The resulting dispersions in solvents are used for chemical functionalization, while dispersion in the HRS solution is used in production of modified polydimethylsiloxane films.
