The invention discloses composite materials, comprising an inorganic nonmetallic mineral as a support and a nanotitania layer loaded on the support, wherein the layer is comprised of a plurality of titania nanospheres, and the titania nanosphere is comprised of a plurality of nanotitania single particles. The invention also discloses composite materials further comprising one or more functional layers loaded on the nanotitania layer. The above composite materials may not only take advantage of the high refractive index and the high covering power of the nanotitania layer, but also make use of the good photocatalytic activity of the small single nanoparticles. Therefore, the application fields of the composite materials are expanded, and the comprehensive performances of the final products are improved. Furthermore, the composite materials can be more readily coated by other functional layer(s) to prepare functionally strengthened or multi-functional composite materials. The invention also discloses methods for preparing the composite materials, which may be carried out with a simple process at low cost. The composite materials of the invention have wide applications and may be used as an additive with good compatibility in various industrial fields.
