Objective
Types of colloids and their fundamental properties; general appearance and shape; formation of particles; colloidal stability as a sum of attractive and repulsive forces; surface reactions; measurement methods; agglomeration; rheology; association colloids; foams; surface physics; structural analysis. The colloidal principles are discussed on many examples. With demonstration experiments and exercises.
Content
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.
