摘要： A method provides a redispersible nanoparticle powder. The method includes: a) providing within a liquid carrier a first dispersion of nanoparticles having surface hydroxyl groups; b) adding a non-metal-ester molecular reactant for the hydroxyl group into the liquid carrier; c) reacting the reactant with the hydroxyl group to form individual, non-continuous sites having reaction product of the hydroxyl group and the reactant to form a surface treated nanoparticle; and d) drying the surface treated nanoparticle to at least reduce the presence of any excess non-metal-ester molecular reactant and providing non-aggregated powder of the surface treated nanoparticles such that when the dried, treated nanoparticle powder is redispersed as a second dispersion in a carrier or solvent having affinity for the non-metal-ester reactant product, a nano-sized particle is formed.
