摘　　要：以苯乙烯为聚合单体,无水乙醇为反应介质,在无氧、无水的条件下进行了纳米铝粉的包裹聚合反应,成功地制备出了粒径为2μm左右,且分布较均匀的球形纳米铝粉微胶囊,并运用SEM、TEM、FTIR、XRD、XPS等测试手段对纳米铝粉微胶囊进行了结构表征。Encapsulating dispersion polymerization in the presence of nano-aluminium was used to prepare the nano-aluminium microcapsules using styrene (St) as monomer and ethyl alcohol as reaction media under the conditions without oxygen and water. The prepared nano-aluminium microcapsules have good sphericity and smooth intact surface, and have size of about 2.0 μm and more uniform size distribution. The nano-aluminium microcapsules were characterized by SEM,TEM,FTIR,X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The results showed that the nano-aluminium powders were uniformly dispersed in PS microspheres and formed nano-aluminium/polymer microcapsules.
