Abstract

The invention relates to the field of super-hydrophobic surfaces. In order to solve the problems of poor binding force between the existing super-hydrophobic SiO2 micro-nano double rough structural layer and a glass substrate and insufficient hydrophobicity, the invention provides a preparation method of the super-hydrophobic surface of glass. The method comprises the following steps of: firstly, preparing fluorosilicone modified acrylic ester emulsion; secondly, preparing modified SiO2 sol; and finally preparing the super-hydrophobic surface of glass. The preparation method is simple and low in cost; a hydrophobic coating has excellent hydrophobicity and has excellent binding force with the glass; and the coating can maintain super-hydrophobicity for a long time.

Description

technical field

[0001] The invention relates to the field of superhydrophobic surfaces, in particular to a preparation method and application of a glass superhydrophobic surface. Background technique

[0002] Surface wettability is one of the important properties of solid surfaces. When the contact angle between solid surface and water is greater than 150°, the surface is superhydrophobic. Professors W.Barthlott and C.Neinhuis of the University of Bonn in Germany, through the observation of the microstructure of the surface of plant leaves, believe that the existence of micron-sized papillae and surface wax on the rough surface makes it super-hydrophobic. On the basis of this research, Academician Jiang Lei and others found that there are nanostructures on the microstructured papillae on the surface of the lotus leaf, revealing the cause of the lotus leaf effect. These findings provide a development direction for the preparation and research of superhydrophobic surfaces. D...
