개질한 지르코니아를 함유한 열경화성 액정 에폭시의 열분해 거동

초록

In this study, liquid crystalline thermosetting epoxy resin (LCTER) was synthesized with 4,4'-diglycidyloxy-α-methylstilbene and sulfanilamide as a basic resin and curing agents, respectively. Following the synthesis, the LCTER composite was fabricated using modified zirconia as a filler. To investigate the thermal behavior of the LCTER composites, a thermogravimetric analysis of the LCTER composites was recorded on temperature difference, with a filler content of 0.5–5 wt% of modified zirconia. The activation energy for the thermal decomposition was calculated using the Kissinger and Flynn–Wall methods. It was found that the activation energies of LCTER composites were proportional to the amount of modified zirconia used in the composites.
