Abstract

The invention provides a preparation method of an antibacterial and bactericidal functional surface. The preparation method comprises the following steps: preparing a bionic lotus leaf micron structure surface; preparing a quaternary ammonium salt cationic polymer monomer; carrying out pretreatment on the surface of the bionic lotus leaf micron structure, then soaking the bionic lotus leaf micron structure in a coupling agent overnight, and grafting bromine active sites on the surface of a substrate; and continuously adding a solvent, the quaternary ammonium salt cationic polymer monomer, a catalyst, a free initiator and a ligand, and removing oxygen, so as to grow a layer of nano polymer brush structure on the surface of the bionic lotus leaf micron structure. The prepared antibacterial and bactericidal functional surface can endow the bionic lotus leaf micron structure surface with super-hydrophobic performance, and the bacterial drug resistance can be reduced; through the synergistic effect between the quaternary ammonium salt cationic polymer monomer and the bionic lotus leaf micron structure surface, the antibacterial and bactericidal functional surface has high sterilization effect and sterilization efficiency, and through the interaction of the component proportion and the process, the antibacterial and bactericidal functional surface has the advantages of being more environmentally friendly, low in preparation cost and efficient in antibacterial effect.

Description

technical field [0001] The invention relates to the field of preparation of functional materials, in particular to a method for preparing an antibacterial and sterilizing functional surface. Background technique [0002] The natural micro-nano structure provides a perfect biomimetic template for the construction of antibacterial functional surfaces, using its own low surface energy properties to reduce the initial adhesion of bacteria and microorganisms on the surface, or by weakening the force between the surface of the material and bacteria, making it The adhesion is not strong, which is easy to remove. Therefore, simulating the surface of natural biological microstructure, using artificial methods to prepare functional antibacterial materials to inhibit the initial adhesion of bacteria on the surface or kill bacteria, provides a safe and effective solution to prevent the harm of bacterial biofilms. However, the current surface used for simple anti-bacterial adhesion cann...
