摘    要:基于1996年以后的40余篇文献和作者的研究成果,综述了层状硅酸盐/聚合物纳米复合材料在制备技术、新品种、新性能、相关理论及应用等方面的最新研究进展,并总结出了以下观点:(1)粘土的有机化是制备纳米复合材料的第一关键要素,单体、预聚体、聚合物熔体与有机土的相容性是制备纳米复合材料的必要条件,外界剪切力可提供帮助;(2)剥离型结构最能体现层状硅酸盐/聚合物纳米复合材料的性能优势,是层状硅酸盐/聚合物纳米复合材料的制备方向;(3)聚合物熔体插层法为简单,是重要的发展方向,要形成剥离型结构,需要同时考虑热力学和动力学因素,基体或相容剂与层间环境的相容性要适中;(4)聚合物乳液共混共凝法有利于传统的制备方法,适合于具有乳液形成的聚合物;(5)在聚合物中原位生成硅酸盐片层的方法具有新意;(6)层状硅酸盐/聚合物纳米复合材料的主要特点是高刚性、高强度、高耐热性、高阻隔性、较好的阻燃性、质轻,目前,该的制备研究正向所有的聚合物品种扩展。汽车部件、包装材料将是层状硅酸盐/聚合物纳米复合材料先应用的两大领域;(7)层状硅酸盐/聚合物纳米复合材料的理论研究进展延慢。界面区状态以及结构-性能间的关系是理论研究的两个主题。

Abstract:Based on the researches of authors and others from 1996 to the present, this paper reviews the latest advances in preparing methods, new materials, special properties, application of layered silicate-polymer(LSP) nanocomposites, and developments in the theory as well. The main viewpoints are as following: (1) Organic modification of clay is the key factor to affect the successful preparation of LSP nanocomposites. Besides, the compatibility between organoclay and monomer, oligomer, polymer melt is necessary, and the shearing force during the preparing process is helpful.(2) Among the 3 possible types of nanocomposites, that is, intercalated, delaminated and a combination of the two, delamination type generally exhibits best performance and is the developing trend of LSP.(3) As the simplest approach, the direct polymer melt intercalation is the important development direction. To prepare delamination type nanocomposites, both thermodynamic effects and dynamic effects must be considered, the compatibility between polymer matrix or compatibilizer and the interlayer environments should be appropriate. (4) Different from the conventional methods, the technique of blending and co-coagulating polymer latex /clay suspension is suitable for polymer with latex; the in-situ hydrothermal crystallization method is also attractive.(5) LSP nanocomposites perform such characteristics as high modulus and strength, outstanding barrier properties, and decreased flammability, originating from the nano-meter size dispersion (thickness) and the large aspect ratio (width/thickness) of layered silicate. Up to now, it seems that all kinds of polymers can be used as the matrix of LSP nanocomposites, which have demonstrated the tendency to be initially applied to automotive and packaging fields.(6)The theoretical research of LSP nanocomposite develops relatively slowly. The interfacial state and the relationship between structure and properties are still the two major subjects.
