Zusammenfassung: | The present invention relates to a method for manufacturing a highly thermally conductive metal-carbon laminate, a laminate produced thereby, and a heat dissipation material using the same. The present invention uses a method of introducing a hydrophilic polymer layer as an intermediate layer between a metal substrate and a carbon-based coating layer to form a strong interface based on chemical bonds and removing the hydrophilic polymer layer through heat treatment. Accordingly, it is possible to manufacture a metal-carbon laminate in which a carbon-based coating layer is uniformly and stably formed on a metal substrate. Therefore, the metal-carbon laminate of the present invention has excellent thermal conductivity and excellent mechanical properties and corrosion resistance, so it is very suitable for use as a heat dissipation material, and in particular, it may be usefully used in the fields of heat dissipation materials for batteries and heat dissipation parts for automobiles which require the above effects.
본 발명은 고열전도성 금속-탄소 적층체의 제조방법, 이에 의해 제조된 적층체 및 이를 이용한 방열 소재에 관한 것이다. 본 발명에서는 금속 기판과 탄소계 코팅층 사이에 친수성 폴리머층을 매개층으로 도입하여 화학적 결합에 기반한 강한 계면을 형성하고, 열처리를 통해 친수성 폴리머층을 제거하는 방법을 이용한다. 이에 따라, 금속 기판에 탄소계 코팅층이 균일하고 안정적으로 형성된 금속-탄소 적층체를 제조할 수 있다. 따라서, 본 발명의 금속-탄소 적층체는 열전도성이 매우 뛰어나고 기계적 특성 및 내부식성이 우수하므로 방열소재로서 사용하기에 매우 적합하며, 특히 상기 효과들을 요구하는 배터리용 방열소재 및 자동차용 방열부품 분야에서 유용하게 사용될 수 있다. |
