Abstract

In this study, a hybrid metals such as copper (Cu) and nickel (Ni) coated carbon fibers (Ni-Cu/CFs) was prepared by wet laid method to develop a randomly oriented sheet material for high-efficiency electromagnetic interference shielding with the enhanced durability. The prepared sheet materials show a high electromagnetic interference shielding efficiency of 69.4 to 93.0 dB. In addition, the hybrid metals coated Ni-Cu/CFs sheets showed very high durability with harsh chemical/thermal environments due to the effective corrosive and mechanical resistances of Ni surface. In this context, the Ni-Cu/CF sheet possesses longer service life than the Cu/CF sheet, that is, 1.7 times longer.


본 연구에서는 향상된 내구성을 가진 고효율 전자파차폐용 랜덤배향 시트 소재를 개발하기 위해 구리(Copper: Cu)와 니켈 (Nickel: Ni)이 코팅된 탄소섬유(Carbon fiber: CF)와 같은 하이브리드 소재를 습식공정을 통해 제조 하였다. 제조된 시트 소재는 69.4~93.0 dB의 높은 전자파 차폐효율을 보여주었다. 또한 하이브리드 금속으로 코팅된 Ni-Cu/CFs 시트는 Ni표면의 유효한 부식저항성과 기계적 저항성 때문에 가혹한 화학적/열적 환경하에서 매우 우수한 내구성을 보여주었다. 이와 관련하여 Ni-Cu/CF 시트는 Cu/CF 시트와 비교하여 1.7배 긴 수명을 가지는 것을 확인하였다.
