摘　　要：埃洛石纳米管(HNTs)是一种天然无机纳米管,和高岭土有相似的化学组成.由于HNTs储量丰富,价格便宜,且具有高模量和大长径比的优势,被科研人员广泛应用于增强和增韧高分子材料的工作中.本文介绍了HNTs的结构特征及表面化学特性,并从提高HNTs在基体中的分散及与基体界面结合的角度,探讨了对HNTs进行表面改性的方法.总结了近十年来HNTs作为增强填料在各种高分子材料中的应用,包括热固性树脂、聚酰胺、聚烯烃和橡胶等.重点关注了所制备复合材料的力学性能,并对聚合物/HNTs复合材料的研究前景进行了展望.Halloysite nanotubes （HNTs） are naturally occurring inorganic nanotubes, which have similar chemical constitution with Kaolinite. Due to their abundance and low cost, combined with superiorelastic modulus and high aspect ratio, HNTs have been widely employed to reinforce and toughen polymer materials. In this review, we briefly summarize the structural characteristics and surface chemical properties of HNTs, Moreover, to improve HNTs dispersion and increase the interfacial interaction between HNTs and polymers, covalent or non-covalent surface functionalization methods for HNTs are utilized. Most importantly, the research progressin the past decade on HNTs reinforced polymer materials which includethermosetting resins, polyamides, polyolefins and rubbers are carefully shown and discussed in detail. Finally, the scientific trends of HNTs/Polymer nanocomposites are proposed.
