More Information
Summary:A near-infrared reflective carbon black composite comprising carbon black and TiO2 coating and a method for making of carbon black composite are disclosed. The method comprises providing a dispersion of a carbon black in a solvent; mixing the dispersion with water and a TiO2 precursor under conditions sufficient to form an oligomer coating comprising a Ti compound on at least a portion of the surface of the carbon black, wherein the TiO2 precursor is at least partially soluble in the solvent; and converting the oligomer coating comprising the Ti compound to TiO2 to form the carbon black composite.
