PS/SiO2-Au organic-inorganic hybrid particles were obtained by reacting organic polystyrene dimer（PsD） with inorganic SiO2-Au particles.The snowman-shape of PsD particles and SiO2-Au particles were obtained via seed emulsion polymerization and sol-gel method,respectively.On the basis of PS/SiO2-Au particles,nano-sized Ag particles were supported on it to obtain bimetallic hybrid particles PS/Ag-SiO2-Au.During the period,effects of the ratios between monomers and polymer seeds,the adding amount of ammonia on morphology of the organic and inorganic particles were discussed.Infrared（FT-IR）,scanning electron microscopy（SEM）,energy spectrum analysis（EDS）,transmission electron microscopy（TEM）and laser particle size tester（DLS） were used to characterize the structure,morphology,composition and size of the obtained particles.The prepared PS/Ag-SiO2-Au hybrid particles will have potential applications in the field of catalysis.
