Abstract
The results of a study of migration of electrically conductive nano-sized carbon particles of different types to the surface of molten polymer composite are presented. The real-time measurements of the changes in electrical conductivity of the polymer composite melt at a constant temperature, carried out separately for the bulk and surface conductivity components, revealed the basic features of the process. The results indicate that the formation of a surface layer saturated with electrically conductive nanoparticles is a general phenomenon for composites where filler nanoparticles with different aspect ratios are used. The role of polymer macromolecules in the kinetics of migration of carbon nanoparticles to the polymer composite melt surface is discussed.
