Outline of Final Research Achievements

Self-repairing polymers have been actively researched all over the world as it enables us to develop novel resins with high durability, long life and high functionality. Conventional self-repairing methods include chemical reaction between functional groups exposed to the damaged part or solidification by leaking monomer solution emcapseled in microcapsules. However, no self-repairing mechanism has been proposed so far that spontaneous filling of microvoids without application of chemical and mechanical forces has been proposed. In this research, we aimed to create polymeric nanocomposites that automatically fill the spaces and recover mechanical and mechanical properties to original state. As a result, we succeeded in developing a polymer that reacts with water vapor and self-heals.
