초록
에폭시 수지는 3차원 네트웍 구조를 갖는 대표적인 열경화성 수지이다. 최근 에폭시 수지의 네트웍 구조를 제어하여 새로운 기능성 에폭시를 개발하는 연구가 활발히 진행되고 있다. 특히, 액정성 에폭시를 대표로 하는 새로운 개질 에폭시는 랜덤한 형태의 네트웍 구조를 배향 구조로 변경함으로써, 기존의 에폭시로부터 얻을 수없는 새로운 기능성 발현에 성공하고 있다. 본 논문에서는 액정성 에폭시 수지의 합성과 고방열성 복합재료로의응용에 관하여 설명하였다.
Abstract
Epoxy resin (EP) is one of the most famous thermoset materials. In general, because EP has threedimensional random network, it possesses thermal properties like a typical heat insulator. Recently, there has been increasing interest in controlling the network structure for making new functionality from EP. Indeed, the new modified EP represented as liquid crystalline epoxy (LCE) is spotlighted as an enabling technology for producing novel functionalities, which cannot be obtained from the conventional EPs, by replacing the random network structure to oriented one. In this paper, we review current progress in the field of LCEs and their application for the highly thermal conductive composite materials.
