以环氧树脂低烟、高效阻燃和良好力学性能为目标，在前期发现的含磷POSS基金属有机超分子阻燃剂（M-P-POSS）在很低含量时即能高效阻燃环氧树脂和显著降低烟释放量和CO释放量的基础上，通过研究结合了过渡金属元素、磷元素和硅元素的M-P-POSS超分子阻燃剂的结构、元素组成，环氧树脂基材、固化网络结构，阻燃剂与环氧树脂相容性、分散状态，阻燃剂组合方式（物理复合、络合作用）等对环氧树脂燃烧行为、烟释放行为和力学性能的影响规律，最终阐明含磷POSS基金属有机超分子M-P-POSS高效阻燃、抑烟机理，并基于此类阻燃剂获得综合性能优异的低烟、低毒、阻燃环氧树脂材料。

For the goal of low smoke, high efficiency flame retardant and good mechanical properties of epoxy resin, a phosphorus-containing POSS based metal organic supramolecular flame retardant M-P-POSS was prepared through the complexation reaction. It was found that M-P-POSS in very low content can effectively improve the flame retardancy of epoxy resin and significantly reduce the amount of smoke products and CO emissions. The project will study the influence of M-P-POSS structure, element composition, epoxy resin network structures, compatibility of flame retardant and epoxy resin, dispersion state of flame retardant, combination styles of flame retardant (physical compounding, complexation) on the combustion behavior and smoke release behavior of epoxy resins composites. Combination with the changes of flame retardant properties, smoke emission and smoke toxicity of different flame retardant epoxy resin systems, the high-efficiency flame retardant and smoke suppression mechanism of phosphorus-containing POSS-based metal organic supramolecular (MP-POSS) was finally clarified. Moreover, a low smoke, low toxicity and flame retarded epoxy resin/M-P-POSS nanocomposite will be obtained.
