Curing Behavior and Morphology of DGEBA/NMA/2,4,6-tris(dimethylaminomethyl) phenol System
DGEBA/NMA/2,4,6-tris(dimethylaminomehyl)phenol 시스템의 경화거동 및 Morphology
Abstract
The investigation of cure kinetics and morphology studies on DGEBA/PEI/Anhydride system were performed by differential scanning calorimetry and scanning electron microscopy. Autocatalystic kinetics model was applied by isothermal scan test. Ozawa method and Kissinger method was applied by temperature scan. Activation energy was 95kJ/mol for neat DGEBA/NMA, 120kJ/mol for DGEBA/PEI(10p.h.r.)/NMA. The generation of secondary phase of PEI was observed and its size was grown up by increasing contents of PEI.
