초록

최근 전자 부품의 소형화, 고집적화가 진행되고 있으며, 소형화된 전자기기는 작은 면적과 얇은 두께로 전자파 간섭 및 발열문제를 해결해야 한다. 그래핀(Graphene) 복합재와 그라파이트(Graphite) 복합재는 가벼우면서도 우수한전기 전도성과 열전도도로 전자파 차폐와 방열 문제를 해결할 수 있는 소재이다. 최근 합성 기술과 복합재 제조기술이 발전함에 따라 그래핀과 그라파이트 복합재를 다양한 분야에 적용하기 위한 연구들이 진행되고 있으며, 본 연구에서는 그래핀과 그라파이트를 이용하여 전자파 차폐 및 방열 특성을 동시에 가지는 복합재 필름을 제안한 최근 연구를 알아보고자 한다.

Abstract

Recently, electronic components are becoming smaller and highly integrated. As a result, electromagnetic interference (EMI) and heat generation problems must be solved simultaneously with a small area and thickness. Graphene composites and graphite composites are lightweight materials that can simultaneously solve EMI shielding and heat dissipation problems with excellent electrical and thermal conductivity. With the recent development of synthetic technology and composite manufacturing technology, the research to application of their composites is increasing. In this paper, we reviewed the latest researches on composite films of graphene and graphite for EMI shielding and heat dissipation.
