Sol-Gel Process: Gels Formation

This lecture covers the formation of gels through the sol-gel process, including physically and chemically crosslinked gels. It explains the percolation threshold, generation concept in polymers, and dendrimers. The process for inorganic materials, hydrolysis, and condensation reactions are detailed. The lecture also discusses the drying and densification of gels, the difference between aerogels and dense solids, and the kinetics of condensation reactions. Various methods for sol-gel processes, advantages, and disadvantages are presented.
