Problems solved by technology

However, on the one hand, these methods are relatively complicated, time-consuming, and have poor repeatability and uniformity; on the other hand, these methods are only suitable for the preparation of relatively small-area titanium oxide films, and are not suitable for the production of large-scale and large-scale titanium oxide films.

Embodiment Construction

[0031] The invention provides a simple, fast and low-cost chemical preparation method of a novel nano-porous titanium oxide film structure material.

[0032] details as follows:

[0033] The first step, the preparation of titanium oxide precursor (such as figure 2 shown)

[0034] 1) Add diethanolamine dropwise to the stirring ethanol, the molar ratio is diethanolamine:ethanol=1:31.2, and stir at 40°C for 10-20 minutes to obtain solution A.

[0035] 2) Add butyl titanate to the above solution drop by drop, the molar ratio is butyl titanate:diethanolamine=1:1.62, and continue to stir at 40°C for 100-150 minutes to obtain solution B.

[0036] 3) Slowly add deionized water dropwise to the above system, the molar ratio is butyl titanate: water = 1:1.26, seal and stir for about 30-40 minutes to obtain light yellow transparent precursor solution C.

[0037] 4) Add a certain mass fraction of polyvinylpyrrolidone (molecular weight Mw=55000) to the light yellow transparent precursor...

Abstract

The invention provides a preparation method of a titanium oxide film and a titanium oxide film. The preparation method comprises the following steps: 1) preparation of titanium oxide precursor; and 2) film coating and after-treatment. The preparation method is simple in preparation technique and can implement large-scale production.

Description

technical field [0001] The invention belongs to the technical field of chemical material synthesis, and relates to a preparation method of a titanium oxide film and a titanium oxide film, in particular to a preparation method of a superhydrophilic porous titanium oxide film and a superhydrophilic porous titanium oxide film obtained based on the preparation method. Titanium film. Background technique [0002] In recent years, semiconductor materials with photocatalytic activity have become research hotspots due to their broad application prospects in photocatalysis, photoelectric conversion and other fields, including titanium oxide, zinc oxide, zinc sulfide, cadmium sulfide, and iron oxide. Among them, titanium oxide is not only chemically stable (acid resistance, alkali resistance, light chemical corrosion resistance), low cost, non-toxic, easy to form a film and has good adhesion to the glass surface, but also has a unique band gap (3.2eV), excellent Its photocatalytic ac...
