摘　　要：介绍了近年来纳米粒子表面包覆的方法与特点,尤其对有机高分子包覆中的聚合化学反应法和自组装高分子法,以及无机物包覆中的沉降与表面化学反应法、声化学法和纳米粒子自组装法给予较为详细的介绍,同时,对生物大分于包覆方法也进行了简要的说明。Surface coating of nanoparticles will present great challenges due to their extremely small dimensions. high surface areas, and high surface energies. This review presents the up-to-date evolvement in strategies of surface coating technology on nano particles. According to the different species of shell materials used in coatings. various methods to synthesize, core-shell particles are classified into three groups: polymer coatings, inorganic coatings and biomacromolecule coatings. Introductions of them are made separately. including polymerization, self-assembly, precipitation and surface reaction etc. The merits and demerits of each strategy were evaluated and compared. The applications and prospects of this technology were also discussed.
