| 摘 要： | 坡缕石是一种层链状硅酸盐矿物。具有独特的纳米棒晶结构。是一种很有潜力的一维纳米增强材料。综述了坡缕石／聚合物纳米复合材料的研究进展，所涉及的聚合物包括丁苯橡胶、丁腈橡胶、聚乙烯、聚氯乙烯、聚苯乙烯、聚丙烯、环氧树脂、双马来酰亚胺树脂(BMI)和聚酰胺等。制备方法包括机械共混法、乳液共混共凝法、溶液共混法、熔融复合法和原位聚合法。研究表明。坡缕石纳米棒晶的分散在制备纳米复合材料的过程中非常重要，而超声波分散是目前最经济有效的方法。还简要论述了对甘肃某地坡缕石提纯并应用于丁腈橡胶制备纳米复合材料的研究。最后展望了坡缕石／聚合物纳米复合材料的应用前景。并对以后需要深入研究的方向进行了分析。

| Abstract: | Palygorskite is one of layered and chained structure silicate,it has unique crystal needle structure and is a potential one dimension nano-intensifier. The article summarizes the progress in nanocomposites of palygorskite/polymer. It deals with many polymers including SBR, NBR, PE, PVC, PS, PP, EP and BMI and some methods involving mechanical blend, latex blend, liquor blend, liquate blend and in situ polymerization. The research indicates that it is important to decentralize palygorskite particles in the process of making nanocoposites and ultrasonic decentralization is the best method at present. The article also discusses the research on the purification of palygorskite in somewhere of Gansu province, the product of which were used in making palygorskite/NBR nanocomposite. At last, the foreground of application of nanocomposites of palygorskite/polymer and aspects in which deeper research is needed were discussed. |
