摘　　要：采用插层法制备了苯酚阴离子柱撑的水滑石,并采用球—壳结构对水滑石进行了表面处理,通过TEM表征,经表面处理后的水滑石粒径分布均匀,更有利于无机粉体在有机树脂基体中的分散.通过DMA表征,表面处理后的球—壳结构水滑石,耐热性能比初级粒子有显著性提高,可作为一种新型结构性超分子自组装功能材料.The intercalation is prepared to make the phenol anion pillared hydmtalcite, the ball-shell structure is used to treat the surface of inorganic uhra-fine powder hydrotalcite. By the TEM images, the hydrotalcite particle size distribution after uniform surface treatment is more conducive to the inorganic powder dispersion in the organic resin matrix. By DMA characterization, the heat resistance of the ball-the shell structure of hydmtalcite after surface treatment is improved, better than the primary particles, which can be used as a new structural supramolecular self-assembly of functional materials.
