Abstract Self‐healing offers promise for addressing structural failures, increasing lifespan, and improving durability in polymeric materials. Implementing self‐healing thermoset polymers faces significant manufacturing challenges, especially due to the elevated temperature requirements of processing. To introduce into thermosets, system must be thermally stable compatible with chemistry.

A latent Grubbs‐type complex bearing two N ‐heterocyclic carbene ligands addresses limitations conventional G2‐based approaches. Under FP's temperatures, catalyst remains dormant until activated by Cu(I) co‐reagent, ensuring efficient dicyclopentadiene (DCPD) upon damage polyDCPD matrix. The two‐part microcapsule consists one capsule containing dissolved solvent, another coagent blended liquid DCPD monomer.
