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. 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 surface self-cleaning glass insulator, which relates to the technical field of glass insulators and comprises a glass insulator main body and a self-cleaning device arranged on the outer side. The self-cleaning device comprises a rotating center arranged around the central axis of the glass insulator main body and a plurality of cleaning brushes connected with the rotating center; each cleaning brush is provided with a brush part and a wind wing part which are oppositely arranged, the outer arc surface of the brush part is attached to the outer surface of the glass insulator main body, and the wind wing part drives the cleaning brush to rotate around a rotating center under the action of wind power; a vibrating part is arranged in the tail end of the cleaning brush, a micro power generation unit is arranged in the rotating center, and the micro power generation unit drives the cleaning brush to rotate through wind power to generate power and supplies power to the vibrating part, so that the vibrating part vibrates to assist the brush part in cleaning the surface of the glass insulator; through the synergistic effect of wind power driving, mechanical scrubbing and vibration auxiliary cleaning, long-term automatic cleaning of the glass insulator is achieved, the stain resistance and operation reliability of the glass insulator are improved, and manual maintenance is not needed.
