Background
In the marine environment, after an object is immersed in seawater, micro fouling occurs on the surface of the object, namely micro organisms such as bacteria and the like are attached to the surface of the object and grow and propagate on the object; spores of macroalgae and larvae of marine invertebrates such as barnacles, mussels and ascidians subsequently attach to the surface of the object, a process known as macrofouling. The marine fouling organisms are attached to the surface of artificial facilities in the sea, which can increase the navigation resistance of ships, block pipelines and culture nets, influence the normal use of acoustic instruments, optical instruments and other offshore equipment, increase the encumbrance of marine oil and natural gas production platforms, accelerate metal corrosion and other serious hazards, and cause huge losses of marine military activities, marine transportation, industry and aquaculture production.
