Physical chemistry of nanodispersed systems and polymer solutions

Objectives of the course:

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.

The course contains selected ideas, laws, models and theories necessary to understand the basic nanotechnology problems.

Synonyms: physics of mesoscale

introduction to nanotechnology

soft matter physics

Physical chemistry of nanodispersed systems and polymer solutions

  • Programming – pascal (FPC) and Surface Evolver
  • 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 stability of colloid suspension. The electric double layer. Colloid stability, DLVO theory. Coagulation kinetics.
  • Conformation of an isolated polymer coil. The Flory-Huggins theory. Other theories of polymer solutions. Polyelectrolytes in solution: electrophoresis, Donnan equilibria.
  • Miscellaneous: Static and dynamic light scattering. Diffusion. Viscosity. Rheology. Effect of polymer on colloid stability, steric stabilization and bridging flocculation,  flocculation, depletion flocculation

Conditions of course crediting

1. Student is obliged to carry out all experiments within the programme and has to present a report on each experiment which is separately credited*

2. The report containing experimental results, calculations, conclusions and responses to the questions given in the description of the experiment should be presented after completion of the experiment of submitted (preferably as a pdf file) to one of the following addresses,

gwnow@amu.edu.pl (reports on experiments 1, 2 and 6)

gnow@amu.edu.pl (reports on experiments 9 and 10)

3. The acceptance of report is credited with 1 point.

4. For presentation of his/her own project and the relevant report the student can score from 0 to 5 points. Report on the project should be submitted to the address

gwnow@amu.edu.pl till 5.06.2013. The final note is given upon review of the report and a possible talk (oral exam) concerning the project.

5. Final notes are presented in the table.

* If a student has a legitimate reason for absence the way of crediting can be individually consulted.
