Embodiment Construction

[0011] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the invention.

[0012] The object of the present invention is to provide a kind of chemical preparation method that does not infiltrate the surface film, this chemical preparation method first prepares a layer of lipophilic and hydrophobic Teflon film on the surface of ITO glass, and utilizes hot air to directly blow the surface while the glue is thrown at a high speed on the surface of the Teflon , volatilize the solution to directly form a solidified layer on the surface.

[0013] In the embodiment of the present invention, while the surface of the teflon is spinning glue at a high speed, the volatilized solvent can...

Abstract

The invention belongs to the technical field of chemical preparation of non-wetting surface films, and provides a chemical preparation method of a non-wetting surface film. The chemical preparation method comprises the following steps: preparing an oleophilic hydrophobic film on a solid surface; in the film surface high-speed whirl coating process, directly blowing hot air onto the surface to volatilize the solution, thereby directly forming a solidification layer on the surface; and annealing and the like to form the film, wherein in the oleophilic hydrophobic film surface high-speed whirl coating process, light radiation quick heating and sample table quick heating can be utilized for quick heating to volatilize the solvent, and hot air is introduced in the whirl coating film formation process to directly volatilize the solvent, so that the solute directly forms the film on the surface. The method is simple, has the advantages of low requirements for equipment, small surface recession and strong practicality, and has high popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of chemical preparation of non-wetting surface films, in particular to a chemical preparation method of non-wetting surface films. Background technique [0002] The use of chemical methods to prepare thin films mainly utilizes the wettability of the solution on the solid surface. In this way, most of the solution is thrown out through the high-speed rotation of the homogenizer, leaving a very thin layer of liquid film on the solid surface. A very thin film can be formed by calcination after drying, but this method cannot prepare a film by spinning a liquid that does not wet the surface. Contents of the invention [0003] The invention provides a chemical preparation method of a non-wetting surface film, aiming to solve the problem that the film cannot be prepared by using the liquid that does not wet the surface by the method of spinning glue when the film is prepared by the existing chemical method.
