综述了近年来国内外对纳米颗粒进行表面改性所采用的包覆方法,包括固相法和沉淀法、溶胶一凝胶法、化学镀法、聚合物包裹法等液相化学法。主要从包覆机理、表征方法、包覆方法及应用进行综述,指出了这些包覆方法的技术关键及优缺点,重点介绍了溶胶一凝胶包覆方法及其应用。并展望了包覆技术的发展前景。
Some fundamental coating methods were introduced, including solid state reaction method and liquid chemistry methods, such as homogeneous precipitation method, sol gel coating method, electroless plating, etc. The coating mechanism, characterization methods, coating methods and their applications were elaborated. Their merits and demerits as well as key processes and conditions were pointed out. The sol-gel method and its applications were emphasized. At last, the foregrounds of coating methods were also discussed.
