Abstract
The present invention provides a thermoplastic resin composition comprising (A) a thermoplastic resin, and (B) a carbon nanofiber-metal composite including a plurality of laminated truncated, conic graphenes continuously coated with a metal. The thermoplastic resin composition according to the present invention can have excellent EMI shielding properties.
Claims16
A thermoplastic resin composition comprising:
- (A) about 50 to about 99% by weight of a thermoplastic resin;
- and
- (B) about 1 to about 50% by weight of a carbon nanofiber-metal composite including a plurality of laminated truncated, conic graphenes continuously coated with a metal, wherein the average length of the carbon nanofiber-metal composite is about 1 to about 10 μm.
A thermoplastic resin composition comprising:
- (A) about 50 to about 99% by weight of a thermoplastic resin selected from the group consisting of polyphenylene sulfides, polyamides, polyalkylene terephthalates, polyacetals, polyimides, polyphenylene oxides, polysulfones;
- polyamide imides, polyether sulfones, liquid crystal polymers;
- polyether ketones, polyether imides, polyolefins, polystyrenes, syndiotactic polystyrenes, and combinations thereof;
- and
- (B) about 1 to about 50% by weight of a carbon nanofiber-metal composite including a plurality of laminated truncated, conic graphenes continuously coated with a metal, wherein the average length of the carbon nanofiber-metal composite is about 1 to about 10 μm.
