Surfactants at the Design Limit

23rd March @ 2:00 pm - 3:00 pm

For common surfactants in aqueous solution the concepts of hydrophilicity and hydrophobicty are well established. Textbooks explain the properties of dilute aqueous bulk surfactant phases in terms of the hydrophobic effect and the Israelachvili-Ninham packing parameter. However, these approaches do not apply so well to surfactant interfacial properties, nor to solvents other than water.The talk will explore the generality of solvopilicity and solvophobicity, as well as the importance of surfactant chemical structure and architecture on interfacial properties. Using this insight it is possible to design and synthesize effective surfactants for non-aqueous solvents, including supercritical CO2.
