ABSTRACT: A hybrid epoxy resin with intrinsic self
healing properties has been prepared from a bifunctional Diels-Alder (DA) adduct.
The obtained network, based on conventional Diglycidyl ether of BisphenolA
(DGEBA) and DA epoxy, leads to simultaneous tuning of physical-chemical
properties and healing capability. The self-repairing behavior has been verified
by means of scratch recovery observation and micromechanical analysis. A
satisfactory morphological and mechanical recovery has been achieved by thermal
stimulus, leading to very promising application in the field of adhesives and
structural applications.
