摘　　要：蒙脱土(MMT)是一种储量巨大且廉价的天然矿物资源,具有独特的片层结构,是增强聚合物材料性能的一种高性价比填料。当MMT在聚合物基体中实现良好分散时,能够明显提高聚合物材料的力学性能、气密性能、热稳定性能和阻燃性能等。但因其表面的亲水性,导致与聚合物相容性差,难以实现良好分散,因此,必须对其进行有机化改性。本文从MMT的结构与改性机理出发,按不同的有机改性剂进行概述,高度凝练了近年来国内外对MMT有机改性方面的研究进展。Montmorillonite(MMT) is a natural mineral resource with huge reserves and low price. It has a unique lamellar structure and is a cost-effective filler to enhance the performance of polymer materials. When MMT is well dispersed in polymer matrix, it can obviously improve the mechanical properties, gas barrier properties, thermal stability and flame retardancy of polymer materials. However, it is difficult to get good dispersion in polymer matrix because the hydrophilicity of its surface leads to poor compatibility with polymers. Therefore, it must be organically modified. Based on the structure and modification mechanism of MMT, the types of organic modifier and research progress in organic modification MMT at home and abroad in recent years were summarized.
