NEW ELECTRICALLY CONDUCTIVE NANOCOMPOSITES BASED ON SILOXANE MATERIALS

Abstract

We report the development of a method for producing long aggregates (more than 1 cm) of multi-walled carbon nanotubes (MWCNTs) dispersed in a solvent by means of directed agglomeration with an electric arc in the liquid phase, as well as study the processes accompanying the formation of these aggregates. A field-oriented carbon agglomerate is obtained and it is found that mica with inclusions of amorphous carbon and agglomerates of nanotubes are formed in such a system. By percolation, the condition of MWCNT crosslinking into the agglomerate at different stress values is established; it is determined that at low concentrations the probability of particle crosslinking is no more than 5%. The obtained results may be of practical interest for the enterprises of power industry in the production of modern types of electrical equipment.
