Abstract:

A method to produce multifunctional nanocomposite materials is presented. Polymer stabilized nanoparticles (e.g. hydroxides, oxides, metals, salts, etc.) are incorporated into a bulk inorganic matrix (zinc oxide/hydroxide, aluminum oxide/hydroxide, ferric oxide, silica, ceria, etc) through the formation of the inorganic phase around the polymer stabilized nanoparticles. This results in the precipitation of a porous nanocomposite that possesses multiple functionalities that come from the different combinations of components of the composite. Nanocomposites that can be used as catalysts, sorbents for heavy metals and arsenic, ion exchangers, and pigments have been made, and data illustrating these properties will be shown.
