INSTRUCTION DESCRIPTION (2) Compared with the prior art, the method of the present invention for processing the surface of an object by laser to have hydrophilicity has the following advantages: First, it adopts the conventional laser processing or laser engraving. The technology, the method is simple, and the process is relatively mature; secondly, the surface structure of the nanometer obtained by laser processing the surface of the object is only in the nanometer level, is not easy to distinguish on the macroscopic, is not limited by the shape of the object, and does not change the overall shape of the object. That is, it does not affect the original appearance of the object; again, the method of processing the surface of the object by laser to make it hydrophilic is able to maintain the hydrophilicity of the surface of the object for a long time. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Referring to the first figure, the present invention provides a processing method for hydrophilizing a surface of an object, comprising the steps of: first providing a substrate to be processed whose surface is hydrophilic; the substrate material comprises: glass, metal or alloy; a laser source, according to the difference of the base material, the glass surface may be processed by using a carbon dioxide laser, or the surface of the metal tantalum alloy is processed by a yttrium aluminum garnet (Nd-YAG) laser; the laser source is irradiated The laser beam is on the surface of the substrate such that a hydrophilic nanostructure is formed on the surface thereof. Among them, the method of processing with a laser source can refer to the conventional laser processing or laser engraving technology, that is, controlling the high-intensity laser light output from the laser source to be focused on the object to be processed, and the computer is controlled to The surface of the object to be processed forms a predetermined shape. Since the power density at the focal point of the laser light is as high as 107 to 1012 watts/cm 2 and the temperature is as high as 10,000 degrees Celsius or more, any material is instantaneously refining and gasifying. Referring to the second figure, the present invention uses a laser method to process the surface of an object.

The above-mentioned nano surface structure obtained by the laser processing of the present invention is significantly reduced by a contact angle (C〇ntact Angie) on the surface of the upper surface of the water, and the surface of the substrate is substantially reduced by t. Since the contact angle shows the scale of the solid surface humidity, the low contact angle table has high humidity (good hydrophilic property) and the surface free energy is low, so the surface of the substrate obtained after processing has good hydrophilicity and, due to the laser method of the present invention. The surface structure of the processed nanometer is only in the nanometer level, and it is difficult to distinguish on the macroscopic scale, and does not change the overall shape of the object, that is, it does not affect the original appearance of the object. In addition, the present invention uses the laser method to process the surface of the object to make it hydrophilic. The nano surface structure can further include other shape structures such as a continuous trapezoidal structure, a continuous rectangular structure or a continuous hump-shaped structure, and only the rice structure is required to be ensured. The pitch? It is 1〇~5 0 0 nm, the depth 1^ is 1〇~1〇〇N, and the surface roughness is 1 〇 nanometer.
