摘要/Abstract

摘要：

有机无机杂化粒子PS/SiO₂-Au通过有机粒子（聚苯乙烯二聚体,PsD）与无机粒子（SiO₂-Au）反应得到,其中雪人形态的PsD粒子和SiO₂-Au粒子分别通过种子乳液聚合和溶胶-凝胶方法制得。在PS/SiO₂-Au基础上,负载Ag纳米粒子得到双金属杂化粒子PS/Ag-SiO₂-Au。期间,分别考察了单体与种子的配比、氨水加入量等对有机和无机粒子形貌的影响;采用红外光谱（FT-IR）、扫描电镜（SEM）、能谱分析（EDS）、透射电镜（TEM）、激光粒度测试仪（DLS）对所得粒子的结构、形貌、成分、尺寸进行了表征。PS/Ag-SiO₂-Au杂化粒子在催化领域有潜在的应用。

Abstract:

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.

Key words: polystyrene dimers, silica, hybrid particles
