Lecture
This lecture covers the thermodynamic aspects of polymer solutions, including the mixing entropy for regular solutions, binary mixtures, and ideal mixtures. It also delves into the concept of solubility parameter, discussing the Hildebrand and Hansen models, and the measurement of cohesive energy. The implications of polymer solubility in various technological applications are highlighted, along with the relationship between solubility parameter, cohesive energy, surface energy, and glass transition temperature.
