Converting Nanoparticles by Surface Modification and Chemomechanical Processing

摘要

Inorganic Nanoparticles can be understood as carriers of interesting functions like UV absorption, porous structure provision, or photocatalytic activity. However, to make these functions available and useful in real world products, additional features are needed with respect to functionality, reactivity, viscosity, solid content, solvent, and pH value. Chemical modification of the surface of nanoparticles can help to meet these requirements. Stabilization of nanoparticle dispersions in the medium of the application is a basic requirement for a nanoadditive system. Starting from agglomerated powders, chemomechanical processing may be used for deagglomeration and simultaneous functionalization of nanoparticles.
