表面活性剂对纳米CaCO3形貌的调控
Shape control of nanocrystals of calcium carbonate by surfactants
【摘要】 分别在AOT/异辛烷/水、CTAB/环己烷/水和OP10/环己烷/水三种不同的反胶束体系中合成出具有不同形貌的纳米碳酸钙,讨论了表面活性剂的类型以及溶剂热过程对纳米碳酸钙的形貌及尺寸的影响.
【Abstract】 Three kinds of shapes of calcium carbonate nanocrystals,which are nanorode,nanotube and nanoparticle,were successfully synthesized in AOT/isooctane/water,CTAB/cyclohexane/water and OP-10/cyclohexane/water reverse micelle systems respectively.The nanocrystals were characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD).The influences of the surfactants and solvothermal condition on the morphology of calcium carbonate nanocrystals were also investigated;the result would help us to deepen understanding of the selforganization mechanism of nanoparticles in reverse micelles.
