Abstract

신규의 초경량 전자기 간섭 차폐 물질 및 상기 물질을 제조하는 방법이 게재되 있다. 직물 섬유는 전기적을 전도성 금속의 시스로 코팅된 직물의 섬유로 결과되는 화학적 증착과정에 놓인다. 직물의 코팅된 층은 이때 선택된 구조적 강도 및 EMI 능력을 가진 금속을 제공하는데 필요한 것으로써 에폭시-메트릭스 화합물로 제조된다.Novel ultralight electromagnetic interference shielding materials and methods of making the materials are disclosed. Fabric fibers are subjected to chemical vapor deposition which results in the fibers of the fabric coated with a sheath of conductive metal. The coated layer of fabric is then made of an epoxy-metrics compound as needed to provide a metal with the selected structural strength and EMI capability.
