笼型六面体倍半硅氧烷 (T8)是一类每个面都由硅氧八元环构成的六面体 ,从它出发可制得以二氧化硅为核心的大分子单体以及无机 /有机纳米复合材料。在叙述了从不同的前驱体制备功能性的 T8方法基础上 ,介绍了从 T8大分子单体出发制备的无机 /有机聚合物纳米复合材料在光固化树脂、耐热阻燃材料、多孔材料、改性高分子材料等领域的应用。 Cage hexahedral silsesquioxane (T8) is a hexahedron composed of eight-membered rings of silicon and oxygen on each side. Starting from this, hexagonal silsesquioxane (T8) can be obtained as macromonomers with silica as the core and inorganic / organic nanocomposites material. On the basis of the description of the functional T8 method from different precursors, the inorganic / organic polymer nanocomposites prepared from T8 macromonomer are introduced in the fields of photo-curing resin, heat-resistant flame-retardant material, porous material, Modified polymer materials and other fields.
