The C–ONbonds in both the alkoxyamine monomer and the cured epoxy are able to be synchronously cleft and recombined, achieving a dynamic reversible equilibrium state. This habit can thus be used as a healing chemistry for repeatedly re-bonding cracked polymer. Moreover, because the nitrile group that possesses strong capability of adsorbing electrons is attached to the carbon atom of C–ONbonds, homolysis
