Description
Technical Field
The invention relates to the technical field of preparation of super-hydrophobic materials, in particular to a preparation method of an anti-bioadhesion super-hydrophobic suspension.
Background
The microorganisms such as protein, bacteria and algae are easy to breed and propagate on the surface of the material, and seriously threaten the life and health of people. According to literature data, the property loss caused by biological adhesion is nearly billion yuan every year around the world, and the number of deaths caused by bacterial infection is nearly millions every year around the world. The loss and harm caused by the growth and mass propagation of microorganisms such as protein, bacteria and algae in the aspects of industrial production, environmental protection, food safety and sanitation are not small and varied.
In recent years, the super-hydrophobic surface has attracted wide attention because of the advantages of hydrophobicity, self-cleaning, ice coating prevention, corrosion prevention, pollution prevention and the like. The superhydrophobic surface refers to a surface on which water has a contact angle of more than 150 ° and a sliding angle of less than 10 °, and the surface has characteristics of low contact area with water and low adhesion. Therefore, the super-hydrophobic material has great prospect in many fields.
The super-hydrophobic surface has low surface energy and high contact angle, and can effectively reduce the adhesion between microorganisms and the surface of a material. However, when exposed to a humid environment for a long period of time, there is a risk of wetting, and microorganisms may attach to the surface to form a biofilm, thereby losing anti-bioadhesive properties. Therefore, an antibacterial agent can be introduced into the superhydrophobic material to obtain a superhydrophobic bioadhesive surface that can weaken the adhesion of microorganisms on a substrate and has bacteriostatic and bactericidal properties, thereby achieving "double-insurance" long-lasting bioadhesive properties. Thus, the synergistic effect of adhesion reduction by hydrophobicity, anti-bioadhesive sterilization is one of the important approaches to the construction of highly effective anti-bioadhesive coatings. Current methods for constructing superhydrophobicity generally have two approaches: (1) the first method is to construct a rough structure on the surface, such as chemical deposition, etching, template, nanoparticle addition, self-assembly, etc.; (2) the second is to modify the surface with low surface energy materials such as silanes and fluorine-containing materials. Although many methods for constructing the superhydrophobic surface exist at present, the methods for constructing the superhydrophobic surface by many methods are complex in process and expensive in equipment, and are not beneficial to large-scale preparation and application of the superhydrophobic surface.
