Based on the requirement of the integration of halogen-free flame retardant, electrical conduction, thermal conduction, hydrophobic properties for the flame retardant polymeric materials used in high-end electrical and electronic field, as well as the critical and common scientific problems of mutual restraint and barrier effect existed in the implement of multi-functional, we will design and assembly construct the flame retardant additive with core-shell-polymer brush structure and the integrated properties of flame retardant, electrical and thermal conduction. The common scientific and technical issues for achieving multi-functional will be solved, and the high-end multi-functional flame retardant polymeric composites will be successfully prepared and applied. The coating of flame retardants, the construction of surface polymer brush, and the assembly of nano-functional materials will be investigated and the novel multi-functional flame retardant additives will be prepared. The interpenetrating network structure of the outer polymer brush layer with electrical and thermal conductive function will be constructed in polymer matrix, meanwhile, the inner flame retardant will present synergistic effect with the outer shell materials. The properties and structure of multi-functional flame retardant additive will be researched, and the effect of its structure and components on the properties of polymeric composites will be deeply investigated, and the effect rule and relationship of dose-effect and structure-effect will be clarified. The distribution of outer functional polymer brush in polymer matrix, the integrity of the interpenetrating network structure and the forming rule will be investigated, and the mechanism of electrical and thermal conduction will be revealed. The theoretical basis will be provided for the development of great potential flame retardant polymeric materials used in high-end application field in the future.
