Learning outcomes

This subject reinforces the knowledge of Ph.D. students in the field of polymer physics. Polymer physics studies polymer conformations, fluctuations, solubility, mechanical properties, etc. Polymers are investigated here using methods of condensed matter physics. Physics of polymers is introduced as a branch of statistical physics and as a part of the science of polymers as well. Polymers are presented in this study subject as extensive and very complex linear molecules. The analysis of their properties is very difficult using straightforward deterministic methods. Therefore, this subject is based on statistical approaches that provide satisfactory results because macromolecules are analytically treatable in the thermodynamic limit of infinitely many monomer units. Students who passed the Master study course "Polymer Physics will concentrate in particular on Chapters 58 of the Syllabus. Those who have not completed this study subject will study chapters 14 individually with the support of consultations.
The student will acquire detailed knowledge of the subject in the area according to the approval of the Branch Board
