摘要
分别以阴离子表面活性剂二(2-乙基己基)丁二酸酯磺酸钠(AOT)和新型表面活性剂二(2-乙基己基)羟基丁二酸酯磺酸钠(AHOT)与异辛烷/水构建的反胶束体系为微反应器,合成了CoFe2O4纳米粒子;利用TGA,XRD,TEM等手段对产物进行了表征;讨论了两种表面活性剂构建的反胶束体系对产物合成过程及纳米粒子形貌和尺寸的影响.
CoFe2O4 nanoparticles have been synthesized from water-in-isooctane reverse micelles. The surfactants used in experiments were bis-（2-ethylhexyl） sodium sulosuccinate （AOT） and bis-（2-ethylhexyl） sodium hydroxy sulosuccinate （AHOT）. AHOT was a new anionic surfactant which was synthesized by our group. Obtained samples were characterized by X-ray diffractometry, thermogravimetric analysis, and transmission electron microscopy. The influence of the surfactants on the process of synthesis, the morphology and the size was investigated. AHOT might have a prosperous prospect in nanopartictes synthesis in the future.
