摘要
用乙二醇为溶剂,三氯化铁和尿素为起始反应试剂,通过一步溶剂热法制备Fe3O4空心微球,经十二烷基苯磺酸钠改性后,以磺基水杨酸为乳化剂和掺杂剂,过二硫酸钾为氧化剂,采用乳液聚合法制备聚苯胺/Fe3O4空心微球复合材料,并利用X射线衍射仪(XRD)、红外光谱(IR)、透射电子显微镜(TEM)和物理特性测试仪(PPMS)表征样品的结构、形貌和磁性能。结果表明:复合材料为形似花状的Fe3O4空心微球均匀镶嵌在丝带网状的聚苯胺中间所构成,复合材料表现良好的磁性。
Magnetite hollow microspheres were successfully synthesized by a solvothermal route,using ethylene glycol（EG） as reaction solvent and FeCl3·6H2O and urea as the starting materials,and it was modified by sodium dodecyl benzene sulfonate（SDBS）.Polyaniline/Fe3O4 magnetic hollow microsphere composites was prepared by emulsion polymerization,using sulfosalicylic acid（SSA） as emulsifier and doping agent and potassium persulfate as oxidant.Phase structure,morphology and magnetic properties of its corresponding products were characterized by X-ray diffraction（XRD）,Fourier transform infrared spectroscopy（FT-IR）,high-resolution transmission electron microscopy（TEM）,and physical property measurement system（PPMS）.The results showed that the composite was composed of the network structure of ribbon-like polyaniline in which flower-like Fe3O4 hollow microspheres were uniformly embedded,and the composite had good magnetic property.
