제목 A Study on Curing and Swelling Behaviors of Epoxy(DGEBA)/Amine(TETA) System
초록 We observed the curing behavior of diglycidyl ether of bisphenol A (DGEBA)/triethylenetetramine (TETA) system using real-time infrared spectroscopy (RTIR) and dynamic mechanical thermal analysis (DMTA), and investigated the swelling behavior of the crosslinked specimens for the system by determining volume swelling ratio (Q) according to the swelling time. RTIR analysis showed that the curing reaction of DGEBA epoxy and TETA amine was a more predominant reaction compared to the homopolymerization of epoxy itself by observing 914 and 1121 cm-1 bands of DGEBA epoxy peak. DMTA experiments revealed that the crosslink density of DGEBA/TETA system increased as the content of TETA was increased. The swelling experiments exhibited that initial swelling rate increased and then rapidly reached to equilibrium state with increasing the content of TETA.
