【Abstract】 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.更多还原
