Preliminaries: intermolecular interactions and thermodynamics in nanodisperse systems. The main types of colloids. Characteristic phenomena in colloid systems. Micelle formation, solubilization. Surfactants at interfaces: wetting, contact angles, surface and interfacial tension, films, foams topology. The electric double layer. Colloid stability, DLVO theory. Coagulation kinetics. Static and dynamic light scattering. Diffusion. Viscosity. Rheology. Conformation of an isolated polymer coil. The Flory-Huggins theory. Other theories of polymer solutions. Polyelectrolytes in solution: electrophoresis, Donnan equilibria. Experimental methods in nanodisperse system studies. Effect of polymer on colloid stability, steric stabilization and bridging flocculation, Q flocculation, depletion flocculation.
The course aims to provide the physical chemistry background necessary for explanation of phenomena and processes taking place in the nanoscale – in colloids, micellar systems and polymer solutions and the achievement of skills of the computer modelling and experimental studies of processes in nanoscales.
Learning outcomes: The course is expected to provide the ability to operate the basic physical laws governing different types of dispersion system, from nanosuspensions and micellar systems to polymer solutions, and to use them in the solution of typical problems of nanotechnology.
