Embodiment Construction

[0024] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0025] The present invention is a kind of imitation bottle grass liquid film fast transport surface texture 1, see figure 1 As shown, it is composed of several structural units 2, and the relationship between them is: identical structural units 2 periodically distributed in the surface texture 1.

[0026] The structural unit 2, see figure 2 As shown, it is composed of the high edges 3 in the structural unit 2 and the low edges 4 in the structural unit 2; the relationship between them is: two adjacent high edges 3 are evenly inserted into the middle of several low edges 4. The structure unit 2 is formed by this; the number of low ribs 4 is determined according to specific requirements, the distance between two adjacent high ribs 3 is determined, and the width and height of high ribs 3 and low ribs 4 are determined By increasing the corresponding number, the dist...

Abstract

The invention provides a sarracenia simulation liquid film quick carrying surface texture. The texture is composed of structure units, the structure units are periodically and circularly distributed in the sarracenia simulation liquid film quick carrying texture which is prepared in the same large area; the structure units are composed of high ridges and low ridges, and the low ridges with a predetermined number are inserted between the two high ridges in an even distribution mode to constitute the structure units in this way, wherein the number of the low ridges which are evenly inserted in an even distribution mode is determined by specific requirements; the width and height of the high ridges are linear ridges, and the sizes of the specific width and height of the high ridges are determined by technology preparation capacity and the requirements; the width and height of the low ridges are linear ridges, the sizes of the specific width and height of the low ridges are determined by the process preparation capacity and the requirements, and the height of the low ridges is lower than the height of the high ridges at the same time. The sarracenia simulation liquid film quick carrying surface structure is simple in structure, is easily prepared in a large area, increases the carrying speed of liquid film and improves the carrying performance of the liquid film.

Description

Technical field [0001] The present invention provides a surface texture for rapid transport of a simulating bottle grass liquid film, which relates to a design of the surface texture of a simulating bottle grass liquid film for rapid transport. Specifically, on the basis of general micro grooves, a part of the edge The height is increased to have a structure with high and low ribs interspersed and distributed. The use of multi-level capillary pulling force enables the liquid film in the micro groove to be transported at a faster speed and larger liquid volume, which belongs to the field of micro-nano manufacturing technology. Background technique [0002] The textured surface of the liquid film for rapid transportation can realize the collection of water mist, the transportation of the liquid film, and the infiltration of the liquid film. This kind of surface can realize the corresponding function only based on the capillary force generated by the microstructure characteristics of...
