Title:

COMPOSITE MATERIAL HAVING IMPROVED ELECTRICAL CONDUCTIVITY AND MOLDED PART CONTAINING SAME

Document Type and Number:

WIPO Patent Application WO/2015/084067

Kind Code:

A1

Abstract:

Provided is composite material obtained by treating resin composition comprising: a thermoplastic resin; bundle-type carbon nanotubes; and an electrically conductive carbon additive, wherein the pre-treatment carbon nanotubes have ID/IG value of 1.0 or less, and the length retention rate of the carbon nanotubes remaining in the composite material post-treatment is 40-99%. The composite material containing the thermoplastic resin can be produced into a variety of molded parts as the electrical conductivity of the composite material is enhanced without degrading the mechanical properties thereof.
