| Abstract: |
| Objective To solve the anti-fog problems of the glass surfaces. Methods TiO2/ SiO2laminated films were coated on the glass substrates to increase the hydrophilicity of the glass. The films were prepared by immersing and pulling out the glass substrate into the solutions which were made by the method of sol-gel. The effects of the preparation temperature of the silicon solution, and the layer numbers of TiO2 and SiO2 on the hydrophilicity of the glass were studied. Results The results showed that the largest influencing factor on the hydrophilicity of the glass surface was the preparation temperature of the silicon solution, followed by the layer numbers of SiO2 . The minimal influencing factor was the layer number of TiO2 . With the increase in preparation temperature of the silicon solution, and the increase of the layers numbers of both SiO2and TiO2, the hydrophilicity of the glass surface first increased, and then remained almost constant. Conclusion The optimal process condition for modifying the hydrophilicity of the glass surface was to prepare the silicon solution at 60 ℃ and coat 2 layers of SiO2 films and 2 layers of the TiO2films on the glass substrates. |
