Outline of Final Research Achievements

Epoxy resins are widely used as electrical and electronic materials, paints, adhesives, composite materials, etc., because of their well-balanced properties such as adhesion, electrical insulation and mechanical strength. In recent years, as the technological innovation of electronic devices such as 5G accelerates, in order to further expand the use of epoxy resins, it is required to improve heat resistance and flame retardancy, which is the biggest drawback of epoxy resins. It was clarified that the heat resistance and flame retardancy of epoxy resin can be significantly improved by the newly developed method in this research.
