Disclosed is a composite material comprising an inorganic non-metal mineral as a support and a nano titanium dioxide layer carried on the support, with the layer consisting of a plurality of titanium dioxide nano spheres and the titanium dioxide nano spheres consisting of a plurality of individual titanium dioxide nano particles. Also disclosed is that one or more multi-functional layers are additionally carried on the titanium dioxide nano layer on the composite material. The composite material not only exerts the advantages of the nano titanium dioxide layer of having a high refractive index and high coverage capacity, but also exerts the good photocatalytic activity of the small individual nano particles therein, and facilitates the coating with other functional layers so as to prepare functionally enhanced or multifunctional composite materials. In addition, a preparation process for the composite material is provided, which is easy and low in cost. The composite material can be used in various industrial fields as an additive, and has good compatibility. |
