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
