270284 VO Colloid and Interface Science (2023W)

Students familiarise themselves with and understand the fundamentals of colloid and interface chemistry and science. Furthermore, how these principles can be applied: for example to understand the nature of the various inter-particle forces, how they can be calculated and applied. Understanding the origins of surface tension and how it can be altered, e.g. by the addition of surfactants, and knowing the nature of different classes of surfactants, and how they modify the properties of interfaces, be they solid, liquid or gas. Introduction into rheological concepts and viscoelasticity.Contents:Particle interactions: van der Waals Forces, Electrical Double layer, the effect of Polymers Kinetic properties of particlesInterfaces: solid-gas, solid-liquid, liquid-liquidSurface/Interfacial Tension and Wetting Surfactants Emulsions Rheology of dispersed mediamethods:lectures about the various topics.
