Lecture
This lecture discusses the swelling behavior of polymers, focusing on the relationship between the polymer structure and its ability to absorb solvents. The instructor explains the impact of different factors on the swelling process, such as the polymer's crosslinking density and the nature of the solvent. The lecture also covers the concept of persistence length in polymer chains and its influence on the swelling behavior. Various equations and parameters related to polymer swelling are presented and analyzed throughout the lecture.
