Effects of Micellar Lifetime on the Macroscopic Phenomena in Surfactant Solutions
The lifetime of micelles has been of a great academic interest in order to understand dynamic behavior of micelles in solution. However, the relevance of micellar lifetime to various technological processes such as foaming, bubble dynamics and emulsification has never been explored. In this study, systematic research has been carried out to delineate the role of micellar lifetime on the dynamic processes in micellar solutions. The pressure-jump technique was used to measure the lifetime of sodium dodecyl sulfate (SDS) micelles. The results showed that the most stable micelles were formed at 200nM SDS concentration and this most stable micellar solution resulted in the least foaming, the largest bubble size and the largest emulsion droplet size.
