This invention discloses a method for improving the hydrophobicity and transparency of glass surfaces. Glass treated with materials such as fluorinated silanes / non-fluorinated silanes is immersed in volatile solvents and treated in an atmospheric or high-pressure reactor at different temperatures (30-300°C) and for different times (1-180 minutes). The treated glass is then cured at 50-300°C for 10-200 minutes to obtain modified glass. This method significantly improves the hydrophobicity of the glass, achieving a water contact angle of 110°-122°, while maintaining the material's transparency (transmittance greater than 95%) and excellent durability. Compared to existing technologies, this invention is simple to operate, low in cost, and has higher durability and adaptability, making it applicable to fields such as self-cleaning glass, waterproof coatings, and optical equipment.

The application discloses a preparation method of frost-proof and dust-resistant self-cleaning glass curtain wall. The method comprises the following steps: depositing nano particles on the surface of glass; etching the glass by taking the nano particles as a template to obtain a mechanically stable nano conical column array structure; grafting liquid-like flexible molecular brushes on the surface of the nano conical column array structure to obtain super-hydrophobic curtain wall surface glass; and assembling the super-hydrophobic curtain wall surface glass into a glass curtain wall. The application provides a self frost-proof technology. Frost crystals are difficult to nucleate on the surface and frost formation is inhibited by the combination of high slip and low adhesion of the liquid-like flexible molecular brushes and the low surface solid area fraction of the rough structure. The frost-proof and dust-resistant self-cleaning glass curtain wall prepared by the application is self dust-proof.
