Abstract
The present invention discloses a method for growing structural titanium dioxide membranes on a titanium base plate, which has the steps that a cleaned titanium foil substrate is put into titanium dioxide suspension liquid, and an impregnation crystal pulling method is used for depositing titanium dioxide powder on a titanium foil base plate; then, the titanium foil base is put into alkaline solution to be sealed for at least 15 hours under 110 to 130 DEG C; after cooling, cleaning by de-ionized water and drying, the structural titanium dioxide membranes are prepared. The preparation method and the use device of the present invention are simple, and have no pollution to environment; the prepared textured titanium dioxide membranes have favorable hydrophilicity than titanium dioxide membranes composed of granules, and the titanium dioxide membranes with the structure have attractive foreground in automatic cleaning.
Description
Technical field
The present invention relates to the method at carrier surface coating titanium dioxide film, is the method for growth texture titanium dioxide film on titanium-base specifically.
Background technology
In recent ten years, the photochemical catalytic oxidation improvement that is applied to environmental contaminants has become the focus of Research of Environmental Sciences.TiO
2As a kind of catalysis material of excellent performance, the organic matter that many chemical methods, bioanalysis etc. can't be degraded can be degraded to CO fully
2, H
2O and corresponding inorganic acid, and with low cost, do not cause secondary pollution, make it very tempting prospect be arranged at aspects such as automatically cleanings.
The glass of using in daily life, pottery, various materials such as plastics can be by dust, and organic matters such as mushroom pollute.The cleaning cost lot of manpower and material resources of these materials.If the surface at these materials scribbles titanium dioxide, can be decomposed by titanium dioxide attached to the pollutant of material surface, need not clean the purpose that yet can keep clean for a long time thereby reach.Titanium dioxide film can be by prepared in various methods on variety carrier.Prepare the anodised method of the main Applied Electrochemistry of titanium dioxide film at present on the titanium foil substrate, this preparation method can cause certain pollution to environment, and prepared titanium dioxide film mainly is made up of titanium dioxide granule.
Summary of the invention
The purpose of this invention is to provide a kind of on titanium-base growth have the method for texture titanium dioxide film of super hydrophilicity.
The method of growth texture titanium dioxide film on titanium-base may further comprise the steps:
1) cleans the titanium foil substrate;
2) with TiO
2Powder is put into deionized water, and ultrasonic oscillation makes tio_2 suspension;
3) the titanium foil substrate is put into tio_2 suspension,, put into the 10-12M alkaline solution then with dip-coating method deposition of titanium oxide powder on the titanium foil substrate, under air-proof condition in 110～130 ℃ of maintenances at least 15 hours, cooling, washed with de-ionized water, drying.
Among the present invention, said TiO
2Powder can adopt commercial TiO
2Powder (P25).Alkaline solution can be NaOH or KOH solution.
The present invention lifts number of times by changing dipping, can control the thickness of titanium oxide film layer.
Beneficial effect of the present invention is:
Preparation method of the present invention and use equipment are simple, environmentally safe; The textured titanium dioxide film that is that makes has better hydrophily than the titanium dioxide film of being made up of particle; And controllable thickness system.
Description of drawings
Fig. 1 is SEM (SEM) photo of texture titanium dioxide film.
The specific embodiment
Further specify the present invention below in conjunction with instantiation.
Example 1
1) with 10% hydrofluoric acid clean titanium foil substrate;
2) with the commercial TiO of 1.0g
2The P25 powder is put into the 20g deionized water, and behind the 5min ultrasonic oscillation, centrifugal 1min gets supernatant liquor under 1000rpm, promptly obtains tio_2 suspension;
3) the titanium foil substrate is immersed in the tio_2 suspension, lifts, deposition of titanium oxide powder on the titanium foil substrate;
4) the titanium foil substrate that will deposit titania powder is placed on 10mL, in the 10M NaOH solution, keeps 15 hours in 110 ℃ under the air-proof condition.Cooling, washed with de-ionized water, drying obtains the titanium dioxide film of texture.
The SEM of prepared titanium dioxide film (SEM) photo as shown in Figure 1, as seen from the figure, this film has the texturing structure.
Experiment shows that this film has good super hydrophilicity, and it is 0 ° that water droplet is sprawled rapidly on this texture titanium dioxide film.So this texture titanium dioxide film has very tempting prospect aspect automatically cleaning.
Example 2
Step is with example 1, and difference is that the titanium foil substrate that step 4) will deposit titania powder is placed on 10mL, in the 12M KOH solution.Kept 15 hours in 130 ℃ under the air-proof condition.
Claims (1)
1. the method for growth texture titanium dioxide film on titanium-base is characterized in that may further comprise the steps:
1) cleans the titanium foil substrate;
2) with TiO
2Powder is put into deionized water, and ultrasonic oscillation makes tio_2 suspension;
3) the titanium foil substrate is put into tio_2 suspension,, put into the 10-12M alkaline solution then with dip-coating method deposition of titanium oxide powder on the titanium foil substrate, under air-proof condition in 110～130 ℃ of maintenances at least 15 hours, cooling, washed with de-ionized water, drying.
