| Application: | LUDOX® TMA colloidal silica along with n-amylamine has been used as surface active particles to stabilize foams from drainage, coarsening and coalescence. Other applications include: • Preparation of porous Bragg mirror and using it for flexible and biocompatible optical interference filters by infiltration of polydimethylsiloxane. • It acts as a filler and surfactant while preparing latexes by miniemulsion polymerization. • As a stabilizer for water-in-cyclohexane miniemulsions to form stable polyurethane shells via interfacial polyaddition. • Synthesis of organic-inorganic nanocomposite films from polyurethane dispersions and colloidal silica particles. |
