I. Introduction
A wide range of applications of carbon nanotubes (CNTs) is based on the unique mechanical, electrical and thermal properties of nanostructures, which is manifested when nanotubes are included in the matrices of various materials and lead to the appearance of new structural-rheological and physicochemical properties of composites. Carbon nanotubes are used as additives to various polymer composites to improve their properties in the manufacture of displays, capacitors and various sensors, anodes, in the role of absorbers of electromagnetic waves [1], [2]. In the practice of producing composite materials, the preparation of a stable dispersed system consisting of a solid dispersed phase and a liquid dispersion medium is important. Solid microparticles, including carbon nanotubes, can be used as the dispersed phase.
