Abstract
A shape-memory epoxy polymer graphene foam composite (SMEP-GrF) is formed from an open cell graphene foam (GrF) surrounded by and infiltrated with a shape-memory epoxy polymer (SMEP) matrix, with the GrF being an intra-connected framework within the SMEP matrix. The SMEP-GrF provides self-healing properties to a device fabricated from the SMEP-GrF. The SMEP-GrF is formed by infusion of an epoxy resin and hardener in an open cell GrF and curing the infused GrF.
