Paper Title:
Study on the Curing Kinetics of Epoxy Resin in Self-Healing Microcapsules with Different Shell Material
  Abstract

The curing process of self-healing microcapsules containing epoxy resin was studied with different shell material such as Poly (urea-formaldehyde), poly (melamine-urea-formaldehyde), Poly (urea-formaldehyde) modified by polyvinyl alcohol, and Poly (urea-formaldehyde) modified by phenol, respectively. The activation energy (ΔE) and the reaction order (n) have been obtained based on Kissinger method, Crane theory and Arrhenius equation. The results showed that: the curing process of epoxy resin as core material in self-healing microcapsules becomes more difficult compared with non-microencapsulated. The stability of shell material impacts on the cure process of core material. The resulting decomposition products of shell materials may participate in the curing reaction. So choosing suitable shell material is particularly important to self-healing microcapsules.
