Dismantlable / Reworkable Epoxy Resins

Abstract

Epoxy polymer networks had limitations in terms of dismantlability and reworkability, due to the chemical covalent network structures. Recently, the molecular design and the composition design of epoxy polymers to enable the dismantlability and the reworkability have been intensively studied, while maintaining the high reliability of the epoxy networks. This article reviews the following items: Reworkable epoxy resin with controlling the chemical decomposition or the thermal decomposition; Dismantlable epoxy adhesives with heat-expansion agents and controlled viscoelasticity; Dismantlable epoxy polymer blends using the dissolvable property or the ion-conductivity.
