Preparation and Characterization of Microcapsules Containing Diets-Alder Reaction-based Self-healable Polymeric Materials and Their Self-healing Property

In this study, the microcapsules containing self-healable polymeric materials based on the Diets-Alder reaction were prepared and the systematic studies about the self-healing property of the microcapsules were performed. Poly(ethylene glycol) chains were applied in the polymerization of furan-polymer to increase the mobility of self-healable materials. The furan-polymer and bismaleimide were introduced into the core of microcapsule, respectively, and these were successfully confirmed using dye modified materials. The relationship between the synthetic conditions and mechanical properties of microcapules was clarified by measurement of capsule strength, and the self-healing ability of macrocapsules in the PMMA-based polymeric composite was confirmed by the release of core materials by OM, SEM and FTIR. These were considered to be originated from the mobility of furan-polymer in the core of microcapsules. Based on these results, it was confirmed that the microcapsules containing the self-healable furan-polymer in this study have the self-healing properties.
