Colloidal Particles: Stabilization and Characterization
This lecture covers the stabilization of colloidal particles through steric stabilization, which involves nonionic dispersants creating repulsion between particles. It also discusses the requirements for polymers to induce steric stability, the thickness of the polymer brush, and disjoining pressure. The lecture further explores the binding of polymers to colloids, the use of scanning electron microscopy for characterization, and the assembly of particles into colloidal crystals. Additionally, it delves into the determination of chemical composition with SEM detectors and the direct assembly of particles on solid surfaces.
