Resin composition for EMI shielding, comprising carbon hydride composite

摘要

Provided is a resin composition for electromagnetic interference shielding. More particularly, provided is a resin composition having superior dispersibility and impact relaxation and high conductivity, the resin comprising: (a) 100 parts by weight of a resin; based on 100 parts by weight of the resin, (b) 0.1 to 15 parts by weight of a carbon nanotube surface-modified in a condition of the absence of oxidant; and (c) 1 to 40 parts by weight of a carbon compound, a metal, a metal compound, or a mixture thereof. The resin composition for electromagnetic interference shielding, comprising a carbon hydride composite, is specifically useful in an electronic control unit material for weight reduction of car, and thus can be replaced with a high-priced heavy metal material.

1. A resin composition for electromagnetic interference (EMI) shielding, the resin composition comprising:
(a) 100 parts by weight of a resin; based on 100 parts by weight of the resin, (b) 0.1 to 15 parts by weight of a carbon nanotube surface-modified in a condition of the absence of oxidant; and (c) 1 to 40 parts by weight of a carbon compound, metal, metal compound, or mixture thereof, wherein
the carbon nanotube surface-modified in a condition of the absence of oxidant is obtained by surface-treating a conductive additive consisting of a carbon nanotube in a subcritical water or a supercritical water condition of a pressure of 50 to 400 atm and a temperature of 100 to 600° C., andat least the carbon compound is not surface-modified in a condition in the absence of oxidant.
