摘　　要：纳米填料具有尺寸小、比表面积高等优点,将纳米填料引入阻垢涂层可进一步提高阻垢涂层的阻垢效果,因此含纳米填料的复合阻垢涂层受到了广泛的关注。本文从纳米填料加入复合涂层后的阻垢机理入手,总结分析纳米填料在阻垢涂层中的作用机理主要有:①低表面能降低成垢物质的成核速率、生长速度及成垢物质在涂层表面的附着力;②表面微纳结构诱发垢层形成不稳定的晶体结构或抑制晶体形核。此外,介绍了纳米二氧化硅、碳纳米材料(碳纳米管、碳纳米纤维、石墨烯及其衍生物等)、纳米金属氧化物(TiO_(2)、CeO_(2)、ZnO)等常用纳米填料的性质及引入涂层后存在的优缺点,总结了纳米填料及阻垢涂层的制备过程及方法,并对纳米填料在阻垢涂层方面的研究方向进行了展望,以期为纳米填料在防垢复合涂层领域的应用提供一定的参考。Nano-fillers have the advantages of small size and high specific surface area.The introduction of nano-fillers into scale inhibition coatings can further improve the scale inhibition effect of scale inhibition coatings.Therefore,the research and application of composite scale inhibition coatings containing nano-fillers have received extensive attention.In this paper,the scale inhibition mechanism of nano-fillers after adding composite coatings was studied,and the mechanism of nano-fillers in scale inhibition coatings was summarized and analyzed:①Low surface energy could reduce the nucleation rate,growth rate and adhesion of fouling substances on the coating surface;②The surface micro-nano structure induced the scale layer to form an unstable crystal structure or inhibited crystal nucleation.In addition,the properties of nano-silica,carbon nanomaterials(carbon nanotubes,carbon nanofibers,graphene and its derivatives,etc.),nano-metal oxides(TiO_(2),CeO_(2),ZnO)and other commonly used nano-fillers and the advantages and disadvantages after the introduction of coatings were introduced.The preparation process and methods of nano-fillers and scale inhibition coatings were summarized,and the research direction of nano-fillers in scale inhibition coatings was prospected in order to provide some reference for the application of nano-fillers in the field of anti-scaling composite coatings.
