Embodiment 1

[0037] When the dot matrix printer used is Epson LQ300K+, at room temperature, use laser etching to modify the micron structure on the surface of the printing needle, the groove size is 6-7 microns, and print on the surface of 0.2mm thick aluminum foil. The contact angle of the aluminum foil surface changed from 49.6° to 68.8°.

Embodiment 2

[0039] When the stylus printer used is Epson LQ300K+, at room temperature, use laser etching to modify the surface of the printing needle with a micron structure, the groove size is 3-5 microns, and print on the surface of 0.02mm thick tin foil. The surface contact angle of tin foil changed from 41.6° to 96.2°.

Embodiment 3

[0041] When the stylus printer used is Epson LQ300K+, at room temperature, use laser etching to modify the surface of the printing needle with micron and nanostructures, the aperture size is 0.1-2 microns, and print on the surface of 0.02mm thick copper foil. The contact angle of copper foil surface changed from 45.4° to 61.8°.

Abstract

The invention belongs to the field of surface modification of solid materials, in particular to a method for changing the surface wettability of thin film materials. The method for changing the wettability of the surface of the solid film material of the present invention is to use an ordinary dot matrix printer at normal temperature to modify the surface of the printing needle with a micron or micron and nanostructure, remove the ribbon, and directly print the film material, which can Micro and nanostructures are printed on the surface of the material, and the change of surface roughness can be used to change the contact angle between the surface of the film material and water, so that the wettability of the surface of the film material can be changed differently. The method of the invention has simple equipment, low cost and no environmental pollution, and can quickly and large-area prepare micron and nanostructures on the surface of the thin film material at normal temperature, thereby changing the wettability of the material surface.

Description

technical field [0001] The invention belongs to the field of surface modification of solid materials, in particular to a method for changing the wettability of the surface of solid thin film materials by using a needle printer. Background technique [0002] Solid surface modification is not only a hot topic in surface chemistry, but also an important research topic in interface engineering. It has very broad application prospects in industrial and agricultural production and people's daily life. After the solid surface is modified, a series of properties such as adsorption, infiltration, and dispersion will change due to changes in surface properties. Wettability is one of the important properties of solid surface. Among the two main factors that determine the wettability of a solid surface, the chemical properties are the internal cause, and the geometric structure and morphology are also an indispensable important factor. Wettability can be ch...
