Abstract

An epoxy/poly(e-caprolactone) (PCL) blend with interesting "bricks (epoxy) and mortar (PCL)" morphology was prepared by polymerization induced phase separation (PIPS). The material is capable thermally mending mechanical damage such as cracks, through an experimentally observed "bleeding" process. Mechanistically, this is due to the volumetric expansionPCL above its melting point in excess of epoxy brick expansion, leading to the extrusion of bulk PCL to fill the crack gap and subsequently recrystallize to restore mechanical strength.
