摘要

OCA-containing microcapsules possessing regular, spherical morphology were created via interfacial polymerization of a polyurethane prepolymer with a small chain diol. Core content comprised more than half of the microcapsule volume at all agitation rates with little weight loss observed after 8 weeks of storage. Future work will continue investigating the effects of the self-healing system on the bulk PMMA tensile, bending, and fatigue properties, assessing the healing efficiency of the incorporated system via crack propagation analyses, and examining the response of MG63 human osteosarcoma cells to the self-healing PMMA formulation.
