聚合物表面修饰层状硅酸盐材料的研究进展

Research Progress in Polymer Surface Modified Layered Silicate Minerals

非离子型、阴离子型和阳离子型3类聚合物都可以对层状结构的硅酸盐进行表面修饰,能够获得新型复合材料。更为重要的是,利用层状硅酸盐表面的活性基团与一些聚合物的活性基团进行缩聚反应,通过共价键结合,将聚合物接枝于层状硅酸盐的表面,能够获得高性能的纳米复合材料。对这类纳米复合材料的研究进展进行了综合讨论,并对其发展前景进行了展望。

Nonionic polymers,anionic polymers and cationic polymmers are employed to modify the surface of the layered silicate minerals. Furthermore, the functional groups located on the surface of the layered silicate minerals and the functionalized polymers are boned via polycondensation and the polymer is grafted onto the surface of the layered silicate minerals. The recent progress in the high performance nanocomposites is reviewed and the future development is prospected in the paper.
