Abstract

The invention provides a super-hydrophilic metal surface micro-nano structure and a manufacturing method thereof. The structure comprises a metal substrate base body, and three groups of mutual-angledparallel groove arrays formed by grooves and prismatic protrusions are formed on the metal substrate base body. The manufacturing method comprises the following steps that firstly, a metal substrateis provided; then the metal substrate is cleaned and dried; then a laser beam is used for scanning the metal surface to obtain the metal substrate with a rough gully-shaped micro-nano structure on thesurface; and finally, deionized water is used for ultrasonically cleaning the metal substrate and the metal substrate is dried. According to the manufacturing method, the rough gully-shaped micro-nano structure is constructed on the metal surface by virtue of a laser etching technology, the super-hydrophilicity is given to the surface of the metal, the structure is simple, and the manufacturing method is environment-friendly, simple and efficient.

Description

technical field [0001] The invention relates to a super-hydrophilic metal surface micro-nano structure and a manufacturing method thereof. Background technique [0002] It has important applications in academic research and industrial technology on solid surfaces with special wettability. These applications include self-cleaning textiles, oil-water separation, anti-icing and anti-fog glass, atmospheric water vapor collection, chemical shielding, and bioadhesion reduction. [0003] There are two main factors affecting the surface wettability of solid materials: the surface roughness of solid materials and the surface energy of solid materials. Super-wetting surfaces can be artificially manufactured by constructing surface micro-nano structures to amplify the intrinsic affinity of substances to certain liquids. The existing methods for artificially manufacturing super-wetting surfaces are mostly polymer coatings and chemical vapor deposition. These methods have shortcomings ...
