摘　　要：介绍了近年来纳米/微米结构粒子的合成技术进展,将纳米单元(纳米棒、纳米带、纳米片、纳米颗粒)自组装为各种尺度的有序结构会产生更优异的整体协同性质,这对纳米/微米结构粒子的性能研究有重要意义。主要介绍了表面活性剂法、水热法和模板诱导法等。表面活性剂由于具有多种特殊、优异的性能,包覆在纳米粒子表面可使其组装成具有新颖结构的聚集体,是目前研究热点。水热法所得粒子具有纯度高、分散性好、晶形可控,生产成本低等特点已被广泛采用。On the basis of introduction of the recent progress in synthesis technique of nano/micron particles,a review has been mainly given to the self-assembly of nano unit,including nanorods,nanobelts,nanofilms,nanoparticles,into multi-scale regular patterned structures.Such self-assembly strategy had paramount importance for the performance of nano/micron particles.The concrete contents mainly include：surfactant method,hydrothermal method and template induction method.Surfactants with a variety of special and outstanding performances,when coated on the surface of nanoparticles,it can lead them assemble into aggregates with new structure.Hydrothermal method has been widely used for its low cost of production,the particles obtained by it had high purity and dispersion.
