摘要
实验绘制了十二烷基硫酸钠(SDS)/正戊醇(n-C5H10OH)-二甲苯[C6H4(CH3)2]-水[或Zn(NO3)2溶液]四组分微乳液体系在不同温度时的拟三元相图.测定了电导率随水(或盐溶液)含量变化的规律,电导的规律与相图吻合.依据电解质理论探讨了微乳液的微观结构,研究表明,温度对油包水(W/O)反相微乳液区域影响不大,电解质的加入对油包水(W/O)反相微乳液区域影响较大.通过SDS/正戊醇-二甲苯-H2O及SDS/正戊醇-二甲苯-盐水的拟三元体系的相图观察及实验研究,选择乳化剂(SDS/正戊醇)与二甲苯质量比为4∶6的微乳液作为最佳条件,制备出了ZnO纳米粒子.
Pseudo ternary phase diagrams and conductivity of SDS/n-pentanol-xylene-water or Zn（ NO3） 2 solution at different temperatures were studied. Pseudo ternary phase diagrams agree well with measure result of conductivity. Microstructure of the microemulsion was also studied via electrolyte theory. The results show that the area of W/O microemulsion changes little with temperature and large with electrolyte solution. The optimum conditions which ZnO nanoparticles were prepared in W/O microemulsion system selected from phase diagram, namely SDS/n-pentanol and xylene,mass ratio is 4∶ 6.
