| Outline of Final Research Achievements |
Continuous thermal and mechanical fatigue causes generation of microcracks in structural polymer materials. The cracks lead to decreased mechanical strength of the materials, eventually resulting in their collapse. Because the cracking occurs in deep region of the materials, it is quite difficult to detect and manually heal it. A novel system for healing the cracks automatically using microcapsules incorporating healing agents is one of life-lengthen of materials.
In this study, we encapsulated a reactive monomer as a healing agent in melamine-formaldehyde microcapsules prepared by the interfacial polymerization method. We could prepare melamine-formaldehyde microcapsules with a content of the reactive monomer of about 40%. We confirmed that epoxy resin incorporating the microcapsules showed healing efficiency of about 32%. These results show that our microcapsules with a high content of healing agents are useful for self-healing of structural polymer materials.
