CARBON NANOTUBE MASTERBATCH, PREPARATION THEREOF, AND USE IN FORMING ELECTRICALLY CONDUCTIVE THERMOPLASTIC COMPOSITION

摘要

An electrically conductive thermoplastic composition is prepared by melt blending a polymer and a masterbatch of carbon nanotubes in wax having a melting point of about 45 to about 150°C. The masterbatch of carbon nanotubes in wax is more easily prepared than a conventional carbon nanotube masterbatch in high molecular weight polymer. Use of the masterbatch of carbon nanotubes in wax also improves the melt flow properties of the electrically conductive thermoplastic composition.
