摘要
采用具有两亲性的嵌段共聚物聚苯乙烯-b-聚二乙烯基吡啶嵌段物(PS-P2VP),与无机前躯体FeCl3和HAuCl4.xH2O在选择性溶剂甲苯中自组装,得到以P2VP/FeCl3/HAuCl4为核、PS为壳的球形胶束;硅片上的胶束经磞氢化钠水溶液还原后用紫外灯降解除去PS-P2VP后得到复合粒子。经场发射扫描电镜、扫描探针显微镜、X射线光电子能谱分析仪等表征及检测,结果表明:在2.2 keV和6.4 keV处分别检测出金和铁元素的信号峰,得到有序排列的金-氧化铁复合纳米粒子。
Amphiphilic block copolymer PS-P2VP,inorganic FeC13 and HAuC14. xH20 can self-assemble into composite micelles composed of a P2VP/FeC13/HAuC14 core and a PS shell in selective solvent toluene. Composite particles were produced by using NaBH4 solution to reduce and UV light degradation to remove PS-P2VP block copolymer. The obtained nanoparticles were characterized by field emission scanning electron microscopy （FESEM）, atomic force microscope （AFM）, and energy dispersive spectrometer （EDS）. Experimental results show that signal peaks of gold and iron are detected at 2.2 keV and 6.4 keV, and a array of composite particles of gold-iron oxide are obtained.
