摘要: 在十六烷基三甲基溴化铵(CTAB)/环己醇/水三组分体系的水包油(O/W)、油包水(W/O)和油水双连续结构区域,以相应盐的水溶液代替水构成3种典型的微乳液体系,分别制备了不同形貌的硫酸钡微/纳结构材料,并通过透射电镜(TEM)、X射线衍射(XRD)手段对所制样品进行了表征。结果表明,微乳液的结构对形成无机盐晶粒的尺寸和形貌能够产生影响,同时CTAB在晶粒表面吸附可能对晶粒的生长起一定的导向作用。

Abstract: BaSO4 micro/nano-structure materials with various morphologies were prepared in three typical O/W,W/O,and BC cetyltrimethylammonium bromide(CTAB)/cyclohexanol/water microemulsion systems formed with the corresponding aqueous solution of salt replacing water,respectively.The as-prepared particles were characterized by TEM and XRD.Results showed that the structures of microemulsion droplets had effect on the size and morphology of inorganic salt particles.Meanwhile, CTAB molecules adsorbed on the surface of particles may be a morphology director during the particle growth.

Key words: micro/nano-structure materials, microemulsion, cetyltrimethylammonium bromide, barium sulfate
