Learning outcomes

The aim of the course is to provide a broad, fundamental basis in surface and colloid chemistry and its applications.

After completing the course, a student should be able to:

• Identify the various types of colloidal systems and classify them according to their thermodynamic stability.

• Identify, describe and predict the phase behaviour of multicomponent systems in terms of molecular properties and self-assembly.

• Understand and describe the nature of surface active agents and the driving forces for their adsorption to various types of interfaces. Calculate the interfacial concentration from surface tension and/or bulk concentration data.

• Explain interfacial charging mechanisms

• Account for the stability or otherwise of a colloidal system in terms of the surface forces acting between the constituent particles and predict behaviour in response to changes in composition.

• Calculate the magnitude of the surface forces acting between arbitrary surfaces/particles in a given medium.

• Understand and apply quantitatively the basic principles of surface thermodynamics to explain and calculate the effect of surface tenson, contact angles, wetting behaviour and related phenomena.

• Explain quantitatively the relationship between adhesion, surface energy and adsorption.

• Identify and describe the surface chemical principles involved in industrial processes such as froth flotation, paper making and detergency.
