Problems solved by technology

[0004] These polymers with good antibacterial and anti-marine pollution properties can mainly be modified on the surface of the material by means of surface-induced polymerization and physical adsorption to improve the anti-fouling effect of the material surface, but these methods are relatively harsh and complex.

Abstract

The invention discloses a method for preparing a surface material with an anti-marine biological pollution function. The surface material with the anti-marine biological pollution function is prepared by soaking and self-assembling anti-pollution copolymer of a dopamine structure onto materials such as titanium, silicon, aluminum, iron and ceramic. The copolymer is applicable to various substances, is environmental friendly and good in anti-pollution property, and is in solid chemical bonding with a substance surface. The process is simple, and the surface material with the anti-marine biological pollution function can be prepared by only directly soaking and drying. The surface material is not only good in marine pollution resistance, but also free of toxicity or pollution, and does not influence the marine environment.

Description

technical field [0001] The invention relates to a preparation method of a surface material with the function of preventing marine biological pollution. Background technique [0002] Marine fouling organisms, also known as marine fouling organisms, are a general term for animals, plants and microorganisms that grow on the surface and bottom of marine underwater facilities. Marine fouling organisms seriously restrict the exploitation, utilization and development of marine resources, causing great harm to marine transportation and the exploration and development of marine resources: increasing the resistance of ships, increasing fuel oil and reducing ship speed; causing marine instrument signals Distortion, performance degradation or even instrument failure; blockage of seawater pipelines on instrumentation facilities; cause anaerobic corrosion of metals, shorten the service life of offshore structures; affect the safety of ships, etc. Economic losses caused by marine biofouli...
