    산화 알루미늄을 분산시킨 열경화성 액정 에폭시의 Mesogen 구조에 따른 열분해 활성화 에너지

    A liquid crystalline thermosetting-epoxy-based composite was fabricated using diglycidyl ether of 4,4’-bisphenol and diglycidyl ether of terephthalylidene-bis-(4-amino-3-methylphenol), with aluminum oxide as a filler, and sulfanilamide and 4,4’-diaminodiphenylethane as a curing agent. Thermogravimetric analysis was performed to investigate its thermal behavior, and temperature differences of the sample were recorded using 1.0−7.0 wt% aluminum oxide. The activation energy for thermal decomposition was calculated using the Kissinger method, and the Flynn-Wall method. The results showed that the activation energy was proportional to the amount of filler added.
