POLYCARBONATE RESIN COMPOSITION HAVING EXCELLENT WEAR RESISTANCE AND ELECTRIC CONDUCTIVITY, AND METHOD OF PREPARING THE SAME

摘要

PURPOSE: A polycarbonate resin composition is provided to ensure excellent wear resistance and an antistatic property required for an antistatic tray due to excellent electric conductivity even if the added amount of carbon black is reduced. CONSTITUTION: A polycarbonate resin composition comprises (A) polycarbonate, (B) styrene-based copolymer resin, (C) carbon nanotube and (D) carbon black. The carbon nanotube and carbon black form a 3-dimensional network structure. The carbon nanotube is selected from the group consisting of single wall carbon nanotubes, double wall carbon nanotubes, multi wall carbon nanotubes, cup-stacked carbon nanofibers in which a plurality of truncated graphenes are laminated, and combinations thereof.
