Mit Kohlenstoff beschichtete inorganische Oxydpartikel und dieselben mit einem Polymerüberzug.

摘要

A porous zirconium oxide particle having a surface which is substantially covered by a carbon cladding. A carbon-clad zirconium or other inorganic oxide particle may have an outermost cross-linked polymer coating. Carbon-clad inorganic oxide particles may be formed by placing a plurality of the particles in a reaction chamber, elevating the temperature within the chamber, reducing the pressure within the chamber, and introducing into the chamber a vapor comprising carbon and thermally decomposing the vapor so as to deposit a cladding of carbon onto the particles. The carbon-clad particles may be coated with a monomer or an oligomer followed by cross-linking the monomer or oligomer to provide polymer-coated carbon-clad inorganic oxide particles.
