摘　　要：微纳马达是一种能被多种能量(化学能、光能、声能、电能、磁能等)激活而发生运动(旋转、穿梭、聚集、扩散等)且尺寸为微米或纳米级的功能器件。其具有体积较小、可控性好、制备简单等优点,在诸如纳米自组装、聚合物降解、药物运输、水污染治理等多个领域展现出较好的应用前景。微纳马达的聚集与分散行为是马达非常重要的群体行为,聚集状态下可大幅提升马达执行任务的效率,分散状态下又可成为独立的个体,各自运动,执行各自的使命。本文概述了近年来微纳马达在聚集与分散行为方面的重要研究进展和最新研究成果,详细叙述不同刺激下两者之间的转换过程及其机理,为深入开展微纳马达动态行为的科学研究提供一定的借鉴和参考。The micro/nanomotors are nanometer or micrometer-sized devices which can be activated by chemical reactions or external physical energy sources（ light energy,sound energy,electric energy,magnetic energy etc.）.The activated micro/nanomotors display rotation,rolling,shuttling,delivery,contraction,or collective behavior. The device has the advantages of small volume,good controllability,simple preparation and so on,and has shown good application prospects in many fields such as self-assembly of nano-particles,degradation of polymers,drug transport and water pollution control. The aggregation and dispersion of micro-nanomotors is a very important group behavior of motor. When aggregated,the efficiency of motors can be greatly improved. In dispersed state,they can also become independent individuals,and exercise their own missions. This article will outline the important research progress and the latest research results of micro-nano motors in gathering and dispersing behavior in recent years,and give a detailed description of the conversion process and its mechanism under different stimuli,which can provide some reference for the in-depth study of micro-nano motor dynamic behavior.
