Abstract
The results of a study of the migration of electrically conductive nanosized carbon particles of various types to the surface of the melt of the polymer composite are presented. The real-time measurement of the kinetics of changes in the electrical conductivity of the melt of the polymer composite at a constant temperature, separately for the bulk and surface components of the electrical conductivity, made it possible to identify the basic features of the process. The results obtained indicate that the formation of a surface layer of a composite saturated with electrically conductive nanoparticles is common when using filler nanoparticles with a different form factor. The role of polymer macromolecules in the kinetics of migration of carbon nanoparticles to the melt surface of a polymer composite material is discussed.
