Abstract
The invention includes a composite material comprising magnetic field responsive particles distributed in a reversibly crosslinked polymer, wherein the reversibly crosslinked polymer includes thermally reversible bonds. In one embodiment, exposing the composite material to an electromagnetic field allows for crack-healing, remolding and/or bonding of the material.
