In order to obtain a comprehensive high-performance polymer material that satisfies the application require- ments under complex working conditions such as thermal field, friction or even damage, in this work, the core- shell structure of Silica sol modified Diphenylmethane diisocyanate (MDI) @Epoxy resin (EP) / F atoms-con- tained-amine (F-A) hybrid was successfully synthesized. After the obtained microsphere material was added as reinforcing filler to the EP substrate, we performed mechanical, tribological, self-repairing and thermal prop- erties characterization. In particular, the resulting composite has a coefficient of friction of only about 0.13 and a thermal conductivity better than 0.2 W / (m K). Here, we provide a new mechanism for efficient self-healing of materials damaged under friction conditions, and impart lubricity and unprecedented heat resistance to the material.
