坡缕石改性及其应用的研究进展

Research Progress on the Modification of Paligorskite and its Development

坡缕石具有许多优良的性能。经过酸活化、硅烷偶联剂表面改性、与高分子基体构成纳米复合材料等物理化学处理后，这些性能可以得到很大改进，因此坡缕石获得更广泛的应用。本文综述了坡缕石的改性方法并介绍了坡缕石在环境保护、绿色农业与新型肥料开发、催化以及脱色等方面的应用进展。

Paligorskite had a lot of excellent characteristic. After the physical chemical treatment as acid activation, surface modification of silane coupling agent and polymer matrix nanocomposites constituted, the characteristic can be greatly improved. Therefore, paligorskite was wild used. The modification of paligorskite and its development of environ- mental protection, green agriculture, development of new fertilizer, catalysis, maeromoleeules and so on were overviewed.
