Phase Diagram of Binary Mixtures

This lecture covers the phase diagram of binary mixtures, including the critical point, binodal, and spinodal regions. It explains the concept of good and bad solvents in polymer solutions, as well as the diffusion of solutes in different concentrations. The instructor discusses the phenomena of nucleation and growth in phase separation, emphasizing the conditions for spinodal and binodal decomposition. The lecture also explores practical applications of phase separation in block copolymers and the behavior of gels, highlighting their mechanical properties and types. Additionally, it delves into the process of gelation and the characteristics of hydrogels, organogels, and aerogels.
