摘　　要：凹凸棒石是具有纤维状晶体结构的天然粘土矿物,属于一维纳米材料。由于其晶体结构和特殊性能,使得凹凸棒石粘土作为优异的补强材料广泛应用于聚合物复合材料。为了提高凹凸棒石粘土在聚合物中的分散性和相容性,对其进行表面改性处理是很必要的。本文综述了纳米凹凸棒石粘土有机表面修饰的研究现状,提出了研究领域现存的问题及其解决方法,分析了产业发展趋势及前景。Attapulgite is a kind of natural clay mineral with fibrous crystal structure and a typical one-dimensional nanophase material. Owing to its special crystal structure and superficial character, it is useful as an excellent filler for polymer composites. In order to improve the dispersivity and compatibility of attapulgite in polymer system, it is necessary to carry on surface modification. Study on surface treatment of attapulgite and application researches ofattaPUlgite as reinforced filler in silicone rubber are presented and come up with ways to improve it.At the end of this paper, the foreground progress of Attapulgite was introduced to the area.The Research of the solving method on the Question of the surface organic modification was showed,and the aspects in which deeper research is needed were discussed.
