액정 폴리머가 열확산 물질로서 유망한 매트릭스로서 주목 받고 있는 이유는? | 액정 폴리머(Liquid crystallin polymer, LCP)는 고도로 배열 된 미세 구조를 가지고 있기 때문에 포논 진동을 통해 효율적인 열전달을 가능하여 열확산 물질로서 유망한 매트 릭스로서 주목 받고 있다. 이와 관련하여 에폭시[22], 아크릴 레이트[23] 및 말레이 미드[24]를 포함한 몇 가지 유형의 액정 성 고분자가 보고되었다. | |
고분자 수지의 열전도도는 무엇의 첨가에 의해 크게 향상될 수 있는가? | 탄소 재료와 세라믹과 같은 유기 고분자와 열전도성 충진제의 합성이 유망한 해결책으로 고려되어왔다[9-12]. 고분자 수지의 열전도도는 충진제의 첨가에 의해 크게 향상 될 수 있지만 가공성 및 기계적 강도 및 내구성과 같은 복합 재료의 중요한 물리적 성질은 고농도의 충진제를 사용함으로써 현저히 감소된다[14]. 보고된 바에 따르면, 고농도 충진제에 의한 문제를 해결하기 위해 열전도성 수지의 합성[15,16], 열전도성 상업용 고분자 가공[17,18] 및 복합체 내 무기 충진제의 배향과 같은 새로운 접근법[19-21] 등 다양한 학계의 보고가 있다. | |
열을 많이 발생시키는 고집적 회로의 개발이 과속화 되면서 발생하는 열과 축적된 열 에너지는 어떤 문제를 일으키는가? | 최근에는 일상생활에서 경량화, 박형(薄型)화, 다기능 전자 기기에 대한 요구가 높아짐에 따라 동작 중 열을 많이 발생시키는 고집적 회로의 개발이 가속화 되고 있다[1-3]. 이러한 열 발생과 축적 된 열에너지는 동작 불량이나 오동작, 내구성 저하 등의 문제를 유발시키게 된다. 따라서 더효율적인 열 발산 재료의 개발은 중요한 문제가 되고 있다 [4-6]. |
