    The goalStudents acquire basic theoretical knowledge on the colloid systems, the importance of particles of colloid size and on their properties.
    The outcomeAfter the students fulfilled all the requirements and passed the exam, they are capable to understand the physico-chemical fundamental principles of colloidal behavior and to apply the acquired knowledge to practical problems in their future work.
    Contents of lecturesBasic definitions of colloid dispersions, true solutions of macromolecules and association colloids (micelles). Preparation and purification of colloidal systems. Determination of particles size and distribution of sizes of particles. Brownian motion, diffusion, sedimentation and osmotic pressure. Optical properties of colloidal systems. Light refraction, scattering and adsorption. Electrical properties of colloidal system. Electric double layer. Electrokinetic phenomena. Rheological properties of colloid dispersions and macromolecular solutions. Surface phenomena. Surface tension. Adsorption at the solid-gas and solid-solid interface. Wetting and spreading. Stability and coagulation of colloid dispersions, true solutions of macromolecules and association colloids. Specific colloid systems – emulsions, foams and gels.
    Contents of exercisesDetermination of molar mass of macromolecules by viscometry. Determination of number average molar mass by osmometry. Determination of tixotropy by rotational viscometry. Determination of surface tension. Determination of electrokinetic potential of colloid particles.
