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 invention relates to the technical field of special glass surface treatment, in particular to a self-cleaning glass etching solution and a surface roughness control method, and the self-cleaning glass etching solution is composed of the following components by weight: 3-8% of ammonium fluoride (NH4F); ammonium sulfate ((NH4) 2SO4): 1-4%; 0.5 to 3 percent of citric acid (C6H8O7); 0.01 to 0.1 percent of sodium dodecyl sulfate (SDS); according to the etching solution for the self-cleaning glass and the surface roughness control method, the stability and the safety of the etching solution are remarkably superior to those of hydrofluoric acid while the etching capability is guaranteed, the safety risk of operators is greatly reduced, and the optical performance and the mechanical strength of the glass are guaranteed to the maximum extent while an ideal self-cleaning micro-nano structure is obtained; the harsh requirements on the performance of the self-cleaning glass in the high-end fields of buildings, automobiles, electronic display and the like are met, and the production efficiency and the product quality stability of the self-cleaning glass are remarkably improved.

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. The deposition and adhesion of dust particles on the surface are 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, so that self-cleaning is realized. The application is simple to use, low in cost and water resource saving.

The invention discloses a preparation method of an indium sulfide-based material for a glass self-cleaning coating. The preparation method comprises the following steps: S1, preparing an indium sulfide powder material; s2, carrying out oxygen plasma reaction on the indium sulfide powder material prepared in the S1 to obtain a T-indium sulfide material; and S3, dispersing the T-indium sulfide material obtained in S2 in a mixed phase of ethylene glycol, water and acetone to obtain a self-cleaning glass coating material solution.
