摘　　要：埃洛石纳米管(halloysite nanotubes,HNTs)作为一种管状的天然矿物材料,在众多领域均有潜在应用价值。结合国内外研究现状,从HNTs的结构特点、表面特性出发,简要介绍了HNTs现有的表面改性方法(物理改性和化学改性),详细阐述了HNTs独特的中空管状结构、大空腔、表面亲水性以及荷电性对膜的物化性质(机械性能、热稳定性、亲水性、Zeta电位)和抗菌防污能力的影响,并对其作用机制进行了分析。同时还对杂化膜中HNTs的中空管状结构、亲水性等特性在气体分子、水分子等的溶解与扩散过程中所起到的重要作用进行了详细描述。此外,基于HNTs优良特性,重点关注了HNTs在膜分离领域的应用:抗菌、防污、油水分离、脱盐、染料分离、气体分离等。最后对HNTs基膜材料的未来可能的应用领域进行了展望,以期在增进对HNTs的认识及设计和制备新型HNTs基杂化膜等方面提供一定的帮助。Halloysite nanotubes(HNTs),a tubular natural mineral material,have potential applications in many fields.Based on the research status at home and abroad,the existing surface modification methods(physical modi-fication and chemical modification)of HNTs were introduced based on the structural characteristics and surface properties of HNTs.The unique hollow tubular structure,large cavity,surface hydrophilicity and surface chargea-bility of HNTs were elaborated.These influence on physicochemical properties(mechanical properties,thermal sta-bility,hydrophilicity,Zeta potential)and antibacterial and antifouling properties of membranes were discussed and the mechanism of action was analyzed.At the same time,the important roles of the hollow tubular structure and hydrophilicity of HNTs in the hybrid membranes in the solution and diffusion of gas molecules,water molecules,etc.,were described in detail.In addition,based on the excellent properties of HNTs,this paper focused on the applications of HNTs in the field of membrane separation:antibacterial,antifouling,oil-water separation,desalina-tion,dye separation,gas separation,etc.Finally,the possible future application fields of HNTs-based membrane materials were prospected,in order to provide some help in improving the understanding of HNTs and the design and preparation of new HNTs-based hybrid membranes.
