Design of Epoxy Resins Based on Heterogeneity in Network Structure and Physical Properties

Abstract

In order to improve reliability in adhesion technologies, a precise control of fracture behaviors and adhesive properties of epoxy resins as well as the prediction of the dulability are strongly desired. To that end, it is necessary to obtain a better understanding of how the network formation and physical state change involved in the curing reaction affect the resultant network architecture and mechanical properties. In this comprehensive paper, we discuss on（i）control for a heterogeneiy in the curing process，（ii）effect of the heterogeniy on solvent cracking in a glassy state，（iii）effect of the cross-linking points in the network on the glass transition dynamics and time-temperature scaling.
