According to the characteristic of silver nanoparticles, their uniform dispersion in reaction media was obtained by surface modification, ultrasonic radiation and the select of emulsion, and then emulsion polymerization system were formed by combination with reactive monomer and initiator. Nano-Ag/Polystyrene core-shell particles were prepared by emulsion polymerization and their microstructure were characterized by TEM, FTIR, XPS, AFM and TG/DTA. The experimental results showed that silver nanoparticles were coated by polymer and the composite particles had typical core/shell structure, and the microlevel combination was realized. Meantime, the form mechanism of nano-Ag/polystyrene core-shell particles was tentatively researched. The conclusion is that the perfect coating was able to obtained by the control of reaction condition.
