Curing Reaction Kinetics of Epoxy/Amine at a Quartz Interface |
| 초록 |
The chemical reaction between epoxy and amine compounds at a solid interface is crucial for the manifestation of the adhesion strength. Here we examined the curing reaction kinetics of epoxy phenol novolac and 4,4'-diaminodiphenyl sulfone at a quartz interface using sum frequency generation spectroscopy, and compared it with the bulk one measured by Fourier-transform infrared spectroscopy. A reaction rate constant (k) was much larger at the quartz interface than in the bulk. While the apparent activation energy at the quartz interface obtained from the Arrhenius plot was identical to the bulk value, the frequency factor (A) at the quartz interface was approximately 5.8 times larger than the bulk one. The results could be explained in terms of the peculiar interfacial aggregation states in which adsorbed epoxy and amine molecules were well-oriented and more closely packed. |
