To study the effect of stereoisomeric structures of curing agents on curing
behaviors, thermal and mechanical properties of epoxy resins, DGEBA(diglycidyl ether of
bisphenol A) epoxy resin and 3,3\'- and 4,4\'-DDS(diaminodiphenyl sulfone) curing agents
were selected. The curing initiation temperature and activation energy of DGEBA/3,3\'-
DDS was lower than DGEBA/4,4\'-DDS. DGEBA/3,3\'-DDS has a faster curing rate and
higher degree of cure than DGEBA/4,4\'-DDS, suggesting that 3,3\'-DDS has higher reactivity
than 4,4\'-DDS. Tensile strength and fracture toughness of DGEBA/3,3\'- DDS was
lower than those of DGEBA/4,4\'-DDS, indicating that mechanical properties of the epoxy
resin can be different only by the stereoisomeric difference in chemical structure of the
curing agent. |
