Abstract
A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and methods for molecular scale healing are provided. The composition can resolve structural defects by a bio-mimetic close-then heal process. In use, the shape memory polymer can provide molecular scale healing in a structural defect. The methods for molecular scale healing can include heating a composition including a thermoplastic such as fibers, particles or spheres to a level at or above the thermoplastic's melting point, then cooling of the composition below the melting temperature of the thermoplastic. The compositions have the ability to close macroscopic defects repeatedly even if another wound/damage occurs in a previously healed/repaired area.
