Problems solved by technology

[0005] However, the hydrophilic polymer coating method is simple, but the formed film is easy to fall off after a long time of use
And adopt the method of coating surfactant, surfactant is easy to lose in water, there is the problem that cannot use for a long time

Embodiment Construction

[0012] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0013] Please refer to FIG. 1. The present invention provides a processing method for making the surface of an object hydrophilic, which includes the following steps: first, a substrate to be processed to be made hydrophilic on the surface is provided, and the substrate material includes: glass, metal or alloy ; Provide a laser source, according to the different substrate materials, can use carbon dioxide laser to process the glass surface, or neodymium-doped yttrium aluminum garnet (Nd-YAG) laser to process the surface of metal and alloy; irradiate the laser beam generated by the laser source On the surface of the substrate, a hydrophilic nanostructure is formed on the surface. Among them, the method of processing with a laser source can refer to the currently known laser processing or laser engraving technology, that is, the high-intensity laser output from t...

Abstract

A processing method which can hydrophilize the surface of body includes the following steps: providing a waiting-manufacture substrate; providing a laser source, and irradiating the surface of the substrate with laser beam generated by the laser source to form a hydrophilic nanostructured. And the spacing of the nanostructured is 10-500 nanometers, the depth 10-100 nanometers, and the surface asperity 1-10 nanometers.

Description

【Technical Field】 [0001] The invention relates to a method for processing the surface of an object, in particular to a processing method for making the surface of an object hydrophilic. 【Background technique】 [0002] Surface hydrophilization processing is a surface processing technology that makes the surface hydrophilic by processing the surface of the material. There are methods for surface hydrophilization, including: hydrophilic polymer coating, surfactant coating and so on. [0003] Hydrophilic polymer coating is to form a layer of hydrophilic polymer film coated on the surface of the base material to make it hydrophilic. [0004] Surfactant coating is to orient the hydrophilic group on the surface of the base material, so that the attached water does not accumulate, and the water film is evenly planarized, showing the hydrophilic effect. [0005] However, the hydrophilic polymer coating method is simple, but the formed film tends to fall off after long-term use. However, w...
