Abstract

Heteroatoms (N, O, and F) and hydrogen groups are important elements for forming the H-bonds. It is well known that a large number of hydrogen groups are formed after curing reaction of epoxy. However, literatures about epoxy resins containing heteroaromatic ring and the H-bonds after cure reaction of the epoxy resins are seldom published. To bridge the gap, a kind of new epoxy monomer containing pyridine ring (EMP) has been synthesized in this work, andit is further cured by 4,4-diaminodiphenyl methane (DDM). The properties of cured EMP/ DDM are evaluated by DSC, DMA, and static contact angle measurement. Moreover, the formation and the role of H-bonds in EMP/DDM are characterized by temperature-dependent FT-IR. The results show that the nitrogen heteroatom in pyridine ring effectively involves in the H-bonds and contributes a lot to the thermo-mechanical performances of cured EMP/DDM. We hope that the results presented in this work can work as a meaningful guide for utilization of the H-bonds to regulate the properties of epoxy resin.
