The adhesion and growth of Marine microorganisms, animals and plants on the surface of Marine facilities form Marine biological fouling, which has a serious impact on Marine industry and Marine engineering equipment. Because of the complexity of Marine environment and the diversity of fouling organisms, the prevention and control of fouling has been an international problem for a long time.

• Ships and Marine equipment are seriously polluted by various kinds of Marine organisms, barnacles, pipe worms, brysworms, mussels and microorganisms such as bacteria and diatoms. Long-term accumulation of biological scale increases navigation resistance of ships, energy consumption and carbon dioxide emissions;
• block the cooling water pipelines of nuclear power plants and thermal power plants, reduce the efficiency of cold and heat exchange, and hinder the normal operation of wave energy power generation and tidal power generation equipment.
• endangers fisheries, such as blocking the mesh of mariculture cages, leading to the death of a large area of fish and shrimp, and reducing the productivity of Marine aquaculture.
