Abstract

This study provides detailed information on the curing system using a catalytic reagent (3-(2-phenyl-1-imidazolyl)propionitrile, 2PZ-CN), which is capable of anionic ring opening polymerization of epoxide as a way to improve thermal conductivity of diglycidyl ether of bisphenol A (DGEBA) epoxy resin. First, reaction behavior of the curing system of DGEBA/2PZ-CN was investigated through dynamic and isothermal DSC measurements, and thermal conductivity of their cured material and composite materials was investigated. The thermal conductivities of DGEBA/2PZ-CN and DGEBA/2PZ-CN/Al2O3(50 wt%) were 0.31 W/m·K and 1.66 W/m·K, respectively, which were about 30% higher values than the general epoxy specimens manufactured under the same conditions.


연구는 diglycidyl ether of bisphenol A(DGEBA)계 에폭시 수지의 열전도도 향상을 위한 방안으로 에폭사이드의 음이온성 개환 중합이 가능한 촉매 물질(3-(2-phenyl-1-imidazolyl)propionitrile, 2PZ-CN)을 활용한 경화 시스템에 대한 상세한 정보를 제공한다. 먼저 2PZ-CN의 경화 시스템에 대해 동적 DSC 및 등온 DSC 측정과 분석을 통해 경화 반응의 상세에 대해 조사하였고, 경화물과 복합재료를 제조하여 열전도도를 분석하였다. DGEBA/2PZ-CN의 열전도도는 0.31 W/m·K, DGEBA/2PZ-CN/Al2O3(50 wt%)의 열전도도는 1.66 W/m·K를 보여, 동일한 조건에서 제조된 범용 에폭시 시료 대비 약 30% 높은 열전도도를 나타냈다.
