Description

Texture structure for antibiosis and product

Technical Field

The invention relates to a texture structure for antibiosis and a product.

Background

The surfaces of objects in the environment are often attached and deposited by microorganisms and grow on the surfaces of the objects to form sources of contamination or pathogens, thereby becoming a threat to human health. Currently, the surface of an object is mainly sterilized by chemical methods, such as by using a disinfectant, such as bleach or ammonia, to sterilize the surface of the object. However, the use of disinfectants can cause secondary contamination of the surface of the object, and the removal of disinfectants can also cause certain environmental pollution. In addition, some antibacterial materials are used for performing antibacterial treatment on the surface of an object through chemical action, and the antibacterial materials are mainly prepared by mixing antibacterial substances or antibacterial material coatings in the materials for sterilizing the surface of the object. However, the antibacterial material is easily attenuated during actual use, and easily falls off under an external environment such as high temperature and high humidity, thereby losing the antibacterial function.

Detailed Description

To facilitate an understanding of the invention, the invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described below. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The invention discloses an antibacterial texture structure which comprises a plurality of distributed micro-nano antibodies, wherein the plurality of micro-nano antibodies are of a convex structure and/or a concave structure, have the same length, can reduce and prevent the attachment of germs, viruses and other microorganisms, can inhibit the propagation of the viruses and bacteria, can inhibit the propagation of the viruses and the bacteria and prevent the formation speed of a biomembrane, and have a good antibacterial effect. When the texture structure is applied to the surface of an object, when a small amount of microorganisms are attached to the texture structure, the propagation, growth and reproduction of the microorganisms are inhibited due to the micro-nano antibodies, and the surfaces of microbial cells or viruses are damaged, so that the aims of physical antibiosis and virus resistance are fulfilled, and a stable antibacterial effect is achieved. The texture structure can be applied to the surface of various objects, including the outer surface and the inner surface, such as medical instruments, daily necessities, baby products, stationery, keyboards, mice, implants and the like, and the physical antibacterial property is stable and long-term, non-toxic and low in cost.

Specifically, the micro-nano antibody defines a length w, a width d, and a depth/height h. Length of the micro-nano antibody: w is less than or equal to 100 mu m; width of the micro-nano antibody: d is more than 0 and less than or equal to 50 mu m; depth/height of the micro-nano antibody: h is more than or equal to 0.5 mu m and less than or equal to 5 mu m; two adjacent micro-nano antibodies are arranged at intervals, and the interval distance is defined as s, wherein s is more than 0 and less than or equal to 10 mu m. The micro-nano antibody selected in the range can achieve a good and stable antibacterial effect, and is easy to form. For example, the plurality of micro-nano antibodies have the same length, the same width and the same height; the spacing distance between the periphery of one micro-nano antibody and other adjacent antibodies can be equal or unequal or variable, and the spacing range is 1 mu m or more and 6 mu m or less. For example, if one micro-nano antibody is obliquely arranged relative to another adjacent micro-nano antibody, the distance between the two micro-nano antibodies is considered to be variable distance, and the range of the narrowest part and the widest part of the variable distance is 1 μm ≦ s ≦ 6 μm. The dimension has deviation due to factors such as process error during specific forming, and all the dimension within 5% can be regarded as having the same length or width or depth or height. The s is a fixed value or an indeterminate value, for example, if one micro-nano antibody is arranged at an included angle relative to the other micro-nano antibody, the s between the two micro-nano antibodies is the indeterminate value, and the s is changed from small to large along with the extension of the included angle.

In one embodiment, the micro-nano antibody arrays are arranged, the micro-nano antibodies in the same line are arranged at equal intervals or variable intervals, and the micro-nano antibodies in multiple lines are arranged at equal intervals or variable intervals.

In one embodiment, the plurality of micro-nano antibodies can also be randomly distributed, and the distance between adjacent micro-nano antibodies is not more than 10 μm. That is, in the plurality of micro-nano antibodies, the maximum distance between two micro-nano antibodies needs to be not more than 10 μm, so that the physical antibacterial effect can be ensured. The random distribution of the plurality of micro-nano antibodies can be local random distribution, random distribution in one direction, random arrangement of a rotation angle, and the like; and when the antibodies are randomly distributed, the distance between adjacent micro-nano antibodies is not more than 10 mu m, so that the stable and reliable antibacterial effect is ensured.

In one embodiment, the micro-nano antibodies are arranged in a plurality of rows, each micro-nano antibody defines a set point at the same position, and the set points of the micro-nano antibodies in the same row are positioned on a straight line or a curve. Preferably, at least a part of the micro-nano antibodies in the same row are rotated from the set point by the same or different angles. When the rotation angle is different, the rotation angles in the same row can be distributed in an equal difference mode, for example, the rotation angles are sequentially rotated within the angle range of 30-120 degrees and with the difference of 0.5 degree.

Specifically, the micro-nano antibody is in a waist shape, a cylindrical shape or a conical shape, and the cross section of the micro-nano antibody is in a rectangular shape, a triangular shape, a trapezoidal shape or a segmental shape. The plurality of micro-nano antibodies have the same shape within a limited size range; or have various shapes within a limited size range, such as a kidney shape and a cylinder shape. For example, when the micro-nano antibody is in a waist-shaped structure, two ends of the micro-nano antibody are semicircular in overlooking angle, and the middle of the micro-nano antibody is rectangular; in the case of a three-dimensional angle, the top surface is a flat surface having a height of 3 μm and is arranged parallel to the bottom surface (bearing surface). For example, the micro-nano antibody is cylindrical, the section of the micro-nano antibody is a semicircle, the micro-nano antibody can also be a base with a certain height, and the base is further provided with a semicircle. The micro-nano antibody is defined as a top surface and peripheral side surfaces, the top surface is a flat surface or an arc surface or a wave surface, and the opposite side surfaces can be arranged in parallel or have included angles.

In one embodiment, the micro-nano antibody is a raised structure or a recessed structure containing an antibacterial material, and preferably, the antibacterial material includes a material having an antibacterial effect, such as nano silver ions or nano metal zinc oxide. Therefore, the texture structure has a sterilization effect, and has chemical sterilization and physical sterilization effects, so that a better antibacterial effect is realized.

The texture structure of the present invention can be formed by the following steps:

step 1: arranging a bearing body with a bearing surface;
