Abstract

Abstract:

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.

Key words: W/O microemulsion; Pseudo ternary phase diagram; Conductivity; Nano ZnO
