摘要

在水溶液/TritonX-100/正己醇/环己烷组成的反相微乳液中，以氯化钡和硫酸钠为原料，通过沉淀反应，制备出类球形BaSO4纳米颗粒，并通过XRD、SEM、TEM、FTIR对其进行表征。考察了三种反应方式、水/TritonX-100摩尔比（R）、反应物浓度以及助表面活性剂/表面活性剂摩尔比（P）对纳米BaSO4颗粒大小和形貌的影响。同时考察了R对微乳液液滴大小和粒径分布的影响，并通过动态光散射技术（DLS）对微乳液液滴进行测定。实验结果表明：室温条件下，采用双微乳液法，R=17.97，P在2.11～4.22之间是纳米BaSO4颗粒合成的最佳反应条件，反应物浓度对BaSO4颗粒的大小和形貌几乎没有影响。在该反应条件下，合成出的类球形BaSO4粒径为18～22 nm，产率可达87.5%。

Abstract

Uniform nano BaSO4 quasispheres were prepared by precipitation reaction with barium chloride and sodium sulfate as raw materials in reverse microemulsion composed of aqueous solution/TritonX-100/n-hexanol/cyclohexane. The product was characterized by XRD (X-ray diffraction)

SEM (scanning electron microscope)

TEM (transmission electron microscope) and FTIR (Fourier transform infrared spectroscopy). The effects of three reaction modes

[H2O]/[Triton X-100] molar ratio (R)

reactant concentration and[co-surfactants]/[surfactants] molar ratio (P) on the size and morphology of BaSO4 quasispheres were investigated. At the same time

the effects of the R on the size and size distribution of micro-emulsion droplets were investigated by dynamic light scattering (DLS). The results show that under room temperature

using double microemulsion method

R=17.97

P between 2.11-4.22 is the best reaction condition for the synthesis of BaSO4 quasispheres

and the reactant concentration had little effect on the size and morphology of BaSO4 quasispheres. Under the reaction conditions

the size of BaSO4 nano-quasispheres was 18-22 nm

and the yield was 87.5%.
