초록

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.

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.
