Abstract

The invention discloses a preparation method for forming a high-transparent and super-lubricating coating on a surface of a glass substrate. The method includes the following steps: 1) cleaning a glass slide with a solvent and drying the glass slide; 2) spin-coating the glass substrate with a toluene solution of a polydimethylsiloxane (PDMS) prepolymer and a curing agent, and curing the solution to form a PDMS coating; 3) soaking the glass substrate coated with the PDMS coating in dimethyl silicone oil so that silicone oil molecules penetrate through the internal skeleton network of the PDMS coating and the surface of the coating. The coating has excellent transparence and is higher than 90% in light transmittance in the wavelength range from ultraviolet to visible light. Contact angle of a water drop on the coating is 109 degrees and the water drop can slip off from the coating very easily, so that the coating has excellent super-lubricating performance. The preparation method is simple and is free of special devices and chemical reagents. The high-transparent and super-lubricating coated glass can be widely applied for manufacturing durable and anti-scratch glasses lens, window glass having self-cleaning function, etc.

Description

technical field [0001] The invention relates to a preparation method of a highly transparent, super-lubricating and self-replenishing coating, which improves the transparency of glass, endows the glass with super-lubricating properties, and expands the application range of the glass. Background technique [0002] Transparent self-cleaning glass is widely used in automobile windshields, building glass screens, displays, solar cells and other fields, and can effectively achieve antifouling, energy saving, economical and other purposes. Researchers used template method (CN103626403A), spin coating method (CN105694715A), sol-gel (CN101362632) and other methods to construct superhydrophobic transparent coatings on glass substrates. However, the steps required by these methods are relatively cumbersome, and the prepared coating has low adhesion to the glass substrate, and it is easy to fall off from the glass surface under the action of external force, which greatly limits the pra...
