Abstract
The invention relates to a method for preparation of a film material, especially coating base material with nano titanium dioxide to prepare a titanium dioxide film on the surface of base material. The technique is characterized in: loading TiO2 into the smooth carrier to form a uniform and continuous film with certain optical characteristic, with nano TiO2, and the carrier metal foil. The prepared TiO2 porous film is cumulated with nano particles, the bore diameter of nano pore passage among tens of to one hundred nanometers. The nano TiO2 film on the surface of metal foil has definite thicken, the TiO2 particles distribute uniformly and the aggregate degree is not large. The technique is simple, the synthesis temperature low, the chemical component even, the pore diameter small and the distribution narrow, and the stoichiometric ratio of TiO2 film and the crystal system well controlled.
