COMPOSITE HAVING IMPROVED CONDUCTIVITY AND PREPARATION METHOD THEREOF

摘要

The present invention provides a composite material having thermoplastic polymers and carbon nanotubes and satisfying the mathematical formula: -3x + 11 <= Log R <= -3x + 16. In the formula, x is parts by weight of carbon nanotubes with respect to 100 parts by weight of the thermoplastic polymer in the composite material; and R is a surface resistance value (ohm/sq) of the composite material. According to the present invention, the composite material has effects of: maintaining excellent thermal and physical properties of polymers; and enhancing conductivity remarkable due to enhanced dispersibility of carbon nanotubes.
