Abstract
Successful dispersion approaches are described for the formation of dispersion of dry powders of inorganic particles. In some embodiments, it is desirable to form the dispersion in two processing steps in which the particles are surface modified in the second processing step. Composites can be formed using the well dispersed particles to form improved inorganic particle-polymer composites. These composites are suitable for optical applications and for forming transparent films, which can have a relatively high index or refraction. In some embodiments, water can be used to alter the surface chemistry of metal oxide particles.
