Abstract:

A process for creating readily or highly dispersible nanoparticles on which chemically reactive functional groups or ligands have been placed. An ultra-high shear fluidic processor is used to change the size distribution of nanoparticle agglomerations and facilitate the formation of stable dispersions of such nanoparticles, as well as the placement of various chemically reactive functional groups or ligands on exposed surface areas of such nanoparticles. Such functionalized nanoparticle agglomerations have a broader size distribution (with a substantial increase in the proportion of smaller agglomerations), can exhibit enhanced dispersion characteristics and, when dispersed in various bulk materials, can impart to such bulk materials the desirable physical or chemical properties associated with the selected chemically active functional groups that have been attached to the surface areas of such agglomerations.
