Abstract
Disclosed herein are an electromagnetic wave shielding thermoplastic resin composition and a plastic article including the same. The electromagnetic wave shielding thermoplastic resin composition comprises about 100 parts by weight of a thermoplastic resin comprising a polycarbonate resin, a polyester resin, or a combination thereof, about 1 to about 30 parts by weight of stainless steel fiber, and about 0.01 to about 10 parts by weight of carbon nanotubes.
Claims11
An electromagnetic wave shielding thermoplastic resin composition comprising:
- about 100 parts by weight of a thermoplastic resin comprising a polycarbonate resin, wherein the thermoplastic resin may optionally comprise a polyester resin;
- about 5 to about 25 parts by weight of stainless steel fiber;
- and
- 1 to about 5 parts by weight of carbon nanotubes wherein an article prepared from the composition has an electromagnetic wave shielding performance of about 60 to about 90 dB, and a notched IZOD impact strength (⅛″) of about 5 to about 30 kgf·cm/cm measured in accordance with ASTM D256.
