Problems solved by technology

It is worth noting that if the conditions are not properly controlled during the preparation of the thin film by this method, it is difficult to obtain a thin film with a good crystal phase, and the metal phase particles of Ti sputtered out during the sputtering process have not had time to fully react before being entrapped. in thin films so that its color is gray

Embodiment 1

[0017] Example 1: After the sample was ultrasonically cleaned with acetone, absolute ethanol, and double distilled water for 10 minutes, it was placed in a vacuum reaction chamber, and the background vacuum was pumped to 4.6×10 -3 Pa, Ar gas (99.99%) was passed into the vacuum chamber, the gas flow rate was 370 sccm, and the chamber pressure was ~2.5 Pa. Turn on the heating to make the chamber temperature reach 320°C, turn on the bias power supply, and adjust the voltage value to 300V. Generate plasma to clean the sample surface for 20 min. Then slowly reduce the bias voltage and turn off the bias voltage. Reduce the Ar flow rate to 66 sccm, turn on the sputtering power supply, the sputtering current value is 12A, and the bias voltage is 200V. After 2min, O 2 , the flow rate is 20sccm, and the sputtering pressure is 4.3×10 -1 Pa. Coating time 3.0 hours. After shutdown, the sample was taken out, and kept in a muffle furnace at 360°C for 10 hours.

Abstract

The invention discloses a method for preparing an ultra-hydrophilic transparent titanium dioxide nano film. The film prepared by the method is about 220nm and transparent and possesses ultra-hydrophilic property without ultraviolet irradiation due to low-temperature annealing; and the film is formed by nano particles which are evenly distributed and have a size of 30 to 45nm, and the crystal structure of the film is anatase phase TiO2. The nano film of the invention can be used in various atomization proof fields such as building glass, automobile rear view mirrors, windshield glass, bathroomglass and the like.

Description

technical field [0001] The invention relates to a preparation method of a superhydrophilic transparent titanium dioxide nano film. Background technique [0002] TiO 2 Due to its unique photocatalysis and ultraviolet light-induced superhydrophilicity, nano-films have great application value on glass surfaces. Even if the moisture or water vapor in the air condenses, the condensed water will not form a single water droplet to scatter the line of sight after being coated with a layer of titanium oxide film , and form a water film spread evenly on it, so the surface will not form light-scattering fog. Even if it is rained, the rainwater attached to the surface will quickly spread into a uniform water film, so that the surface of the film maintains a high degree of transparency. Currently TiO 2 Nanofilm research mainly focuses on the superhydrophilic TiO induced by ultraviolet light 2 (or doped TiO 2 ) Nanofilms, related to superhydrophilic TiO without UV light 2 Nano-film...
