Title
Molecular Thermodynamic Modeling of the Micellization Behaviour of Surfactants
Abstract - Surfactants find a wide range of application in both academia and industry. In addition to their historical use in cleaning agents and personal care products like shampoos and conditioners surfactants have found use in several other applications which include areas like pollution remediation drug delivery and enhanced oil recovery. The talk focuses on the development of a molecular thermodynamic model to predict the micellization properties of surfactants namely the critical micelle concentration the micelle size shape and aggregation number. The applicability of the model is tested by comparing the model predictions against experimental data for linear hydrocarbon based surfactants. Ongoing work towards the application of the model to predict the coexistence of two types of micelles in a surfactant solution containing mixture of fluorocarbon-based and hydrocarbon-based surfactants is also discussed.
