Synopsis

This unit lays a foundation of knowledge about the characterisation and behaviour of colloid sized particles and the role their surfaces play in determining this behaviour. It also provides an introduction to the structure and behaviour of surfactant based systems.

This will involve:

colloidal systems
sedimentation and diffusion
osmotic pressure
rheology
surface tension and contact angles
insoluble and soluble monolayers
surfactant systems
van der Waals forces
electrical double layers and Electrokinetics
colloid Stability and DLVO theory

Outcomes

At the end of this unit students will be able to:

Describe lyophilic and lyophobic colloids;
Differentiate between and illustrate kinetic and thermodynamic stability;
Differentiate between solutions and dispersions;
Define and describe rheological behaviour of suspensions and solutions;
Predict suspension stability in terms of DLVO theory;
Describe DLVO theory and its components;
Describe different types of interaction that can occur between particles in different concentration of polymer - both adsorbing and non-adsorbing;
Illustrate and describe the total energy of interaction between surfaces.
