Self-healing polymers are able to repair themselves after being damaged. Microcapsules were prepared to contain both a healing agent, dicyclopentadiene (DCPD), in addition to a damage detection agent, 1,3,5,7-Cyclooctatriene (COT). The DCPD-COT microcapsules were ruptured in the presence of Grubbs’ catalyst, and color change was confirmed. Modified compact tension specimens were produced that contained DCPD and DCPD-COT microcapsules. Voids within the polymers prevented the specimens from healing, so the effect of COT on the healing efficiency could not be tested.
