Course information

Content and learning outcomes

Course contents *

Colloid chemistry is the oldest branch of chemistry predating even alchemy. However, the knowledge base of colloid chemistry began to fade from the chemistry curriculum and has only recently had a resurgence due to the importance of nanoparticles. The importance of the basic science of colloid chemistry will be briefly reviewed. Optical experiments (absorption, fluorescence, time-resolved fluorescence, dynamic light scattering etc.) can now be used to elucidate the surface coverage and electrostatic properties of nanoparticles.

Colloids and colloidal principles are widespread in daily life, in nature and technical application. Why is milk white and some tooth pastes transparent? What are colloids and what is their behaviour? Colloids are mixtures of different phases and diverse and complex appearance. What can we expect of such systems, how can we use their properties and how can we use their properties. With lots of examples from the daily life in the area of materials and of food, with key experiments, this lecture concerns the interdisciplinary and very broad topic of the colloids.

Main contents are:

- Colloidal (nano) Particles

- Intermolecular Forces and Van der Waals Forces between Colloidal Particles

- Surfaces and Interfaces in colloidal systems including Surface Tension and Interfacial Tension

- Wetting on Surfaces including wetting in Porous Media including contact angles and dynamic wetting

- Electrical Phenomena at Interfaces like Electrical Double Layer, Electrokinetic Measurements and Interaction of double layers

- Colloidal Stability and Kinetics of Coagulation
