Abstract

A method of producing functionalized surface-modified alumina by adding an organic modifier comprising acrylic acid to alumina and drying the alumina to covalently bond the organic modifier to the surface of the alumina. The functionalized surface-modified alumina being uniformly dispersible in organic polymer to form single crystallites of functionalized surface-modified alumina in the polymer.
