Effects of ultrasound on the microenvironment in reverse micelles and synthesis of nanorods and nanofibers

FTIR and UV-vis techniques were used to investigate the effect of ultrasound on the microenvironment of sodium bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelles in iso-octane. The studies revealed that ultrasound resulted in re-aggregation of the reverse micelles and thus enlarged the water core of the micelles. On the basis of these investigations, ZnS nanorods and nanofibers were synthesized in the reverse micelles by the ultrasound-induced method. A possible mechanism for ultrasound-induced formation of nanorods and nanofibers in reverse micelles is discussed.
