Patent ID: 8865798

Claim:
A self-healing material comprising a matrix including: micropockets containing a healing-agent, said healing agent comprising 5-ethylidene-2-norbornene; and microcapsules containing a liquid that is a PDMS oil, and mixtures thereof, and a catalyst dissolved or dispersed in the liquid and allowing the polymerization of the healing agent, said liquid being effective for protecting said catalyst from water and said liquid being effective for not interfering during the polymerization of the healing agent, said micropockets and said microcapsules being uniformly distributed and embedded in the matrix, being understood that when a crack is made in the matrix, at least one micropocket of the set of micropockets and one microcapsule of the set of microcapsules are broken to release and mix their content in the crack and thereby allow the polymerization of the healing agent <<in situ>> into a solid polymer that is bonded to the matrix and fills the crack to repair it.
