Abstract
Shape memory polymer (SMP) epoxies and composites, and methods of manufacturing the same, are provided. A three-dimensional (3D) printing technique can be used to fabricate a pure thermoset SMP epoxy. A cryogenic sprayer assisted extrusion type 3D printing method can be used to print SMP epoxies and composites of an SMP epoxy and a nanomaterial additive, such as graphene nanoplatelets (GNP).
