Marine biofouling will increase the weight of the ship,accelerate the corrosion rate of the hull,and increase the greenhouse gas emissions,which will greatly pull up the ship operation cost.The focus was on the research progress of antifouling coating with low surface energy such as organic silicon and organic fluorine for antifouling and drag reduction of ship hulls,and explained their advantages and disadvantages in applications.The principle of antifouling and drag reduction based on the surface microstructure of marine organisms and the preparation method of the microstructure surface were analyzed.The effects of antibacterial substances,especially antibacterial peptides on the surface of modified substrates,on the adhesion of fouling organisms were reviewed.The effects of surface structure and surface substances on the antifouling of the hull surface were compared.Finally,the application prospects and development of low surface energy antifouling coating technology were prospected.
