摘要： 采用水(溶液)/TritonX-100/环己烷/正戊醇微乳体系,制备片状PbSO4纳米晶,并利用TEM对产物进行了表征.考察并初步讨论了微乳体系中几种因素对其尺寸及形貌的影响以及PbSO4纳米晶在微乳液中的生长和自组装机制.

关键词: W/O微乳液, 硫酸铅, 纳米片晶, 液相自组装

Abstract: Plate-like nanocrystal PbSO4 was synthesized in quaternary W/O microemulsion system containing water, Triton X-100, cyclohexane and n-pentanol. Transmission electron microscopy(TEM) was utilized to characterize the morphology of PbSO4 as-prepared and electron diffraction(ED) analysis identified the crystal nature of the product. Two key variables-X0(molar ratio of water to surfactant) and reactant concentration in water were investigated to reveal the formation and self-assembly mechanism as well as the shape and size changing of plate-like nanocrystal PbSO4 under different conditions.

Key words: W/O microemulsions, PbSO4, Plate-like nanocrystal, Self-assembly in liquid phase
