Students will obtain genereal view of conditions of existence of colloidal systems, of properties and preparation of the most important types of those systems and their significance for industrial practice.

Basic physical chemistry, particularly thermodynamics, electrochemistry, and colloid chemistry.

Not applicable.

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

The exam is realized by individual student's project and written part. Student works out and presents orally an essay on suitable topic from the contents of the course. Oral presentation includes general discussion on theoretical basis of presented topic. The written part consists of ten questions which should be answered in one phrase each within the time limit of 50 min.

1. Classification of colloids, their significance in consumer's industry. Intermolecular forces - overview.
2. Intermolecular forces - typology.
3. Intermolecular forces - mathematical treatment.
4. Intermolecular forces between colloidal particles.
5. Formation and preparation of colloids.
6. Stability and stabilization of colloids.
7. Tensides - functions, classes, properties, detergency.
8. Gels - structure, properties, preparation, characterization, practical application.
9. Emulsions - structure, properties, preparation, characterization, practical application.
10. Suspensions - structure, properties, preparation, characterization, practical application.
11. Foams - structure, properties, preparation, characterization, practical application.
12. Aerosols - structure, properties, preparation, characterization, practical application.
13. Adhesion and wetting, adhesive types.

Not applicable.

Aim of the subject is to present theoretical foundations for behaviour of colloid systems and inform on colloids substantial for the applied chemistry from the viewpoint of their preparation, structure and properties.
