Problems solved by technology

However, the raw materials used in the precursors of the sol-gel method are generally expensive titanium-containing alkoxides, and the preparation of the gel requires a large amount of organic solvents, the cost is relatively high, and the adhesion between the film and the substrate is poor. Easy to crack during the process
The titanium dioxide film prepared by the hydrolysis-precipitation method has a relatively uniform film structure and good adhesion, but the reaction conditions need to be strictly controlled during the preparation process
At the same time, the titanium salt required for the preparation of the solution, such as TiCl 4 , or more toxic
Although the liquid phase deposition method does not require expensive equipment and is simple to operate, it utilizes the chemical equilibrium reaction between fluorine titanium ions and titanium dioxide in the aqueous solution, combined with the complexation effect of the introduction of boric acid in the solution, deposits titanium dioxide into the impregnated On the carrier in the reaction solution, but the preparation process takes too long, and the metal complex ions of fluorine may have an impact on the environment

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation methods, in particular to a preparation method of titanium dioxide nano film. Background technique [0002] Nano-titanium dioxide is a semiconductor material with a wide bandgap width. It has excellent optical, electrical and chemical stability properties. It has been widely used in the fields of semiconductors, sensors, dielectric materials, coatings and catalysts. But the use of its superior optical, electrical and magnetic properties is mainly in the form of titanium dioxide thin films. The photocatalysis of titanium dioxide can occur on the surface of the irradiated titanium dioxide. However, the powdery photocatalyst titanium dioxide has disadvantages such as easy deactivation and difficult recovery, which limits its application. In addition to solar energy conversion, under the irradiation of ultraviolet light, titanium dioxide film also has novel functions such as air puri...
