Abstract

A liquid crystalline thermosetting-epoxy-based composite was fabricated using diglycidyl ether of 4,4'-biphenol, tin(IV) oxide as a filler, and sulfanilamide as a curing agent. To investigate the thermal behavior, Thermogravimetric Analysis and Laser Flash Apparatus were performed using 3.0−7.0 wt% Tin(IV) oxide. The result showed that the activation energy and thermal conductivity were proportional to the amount of added filler


Diglycidyl ether of 4,4'-biphenol을 기지로 사용하고, tin(IV) oxide를 filler로, sulfanilamide를 경화제로 사용하여 액정성 열경화성 에폭시 기반 복합재료를 제작하였다. TGA와 LFA를 이용하여 3.0-7.0 wt%의 tin(IV) oxide를 분산시켜 제작한 복합재료의 열적 거동을 조사한 결과, 열분해 활성화 에너지와 열전도성이 filler의 첨가량에 비례하는 것으로 나타났다


Keywords: 열경화성 액정 에폭시(Liquid crystalline thermosetting epoxy), 산화주석(Tin oxide), 열분해 활성화 에너지 (Activation energy for thermal decomposition), 열전도도(Thermal conductivity)
