Abstract:
1. A composite comprising a reversibly crosslinked thermoset polymer, wherein magnetic field responsive particles are dispersed within the composite, wherein the Curie or Neel temperature of the particles is lower than 150° C., wherein the reversibly crosslinked thermoset polymer is generated by forming covalent bonds among a plurality of monomers, wherein each covalent bonds formed by polymerization of the plurality of monomers is a thermally reversible covalent bond, wherein applying an electromagnetic field of given strength alternating at a first frequency to the composite heats the composite to a first temperature at which a portion of the thermally reversible covalent bonds is broken, and wherein the first temperature is lower than the temperature at which the polymer undergoes irreversible decomposition.
