With the increasing awareness of environmental protection,environmentally friendly and broad-spectrum new antifouling coatings have become a current research hotspot in the field of marine antifouling.The formation process of biofouling and the fouling mechanism were outlined,and the research progress of new environmentally friendly antifouling coatings in recent years was summarized,including fouling-release antifouling coatings,photocatalytic antifouling materials and natural antifouling agents derived from biomimetic strategies,hydrogel antifouling coatings,etc.The mechanism of action of antimicrobial peptides and the means of preparation of modified surfaces were highlighted.It was pointed out that this type of antifouling material has broad-spectrum antibacterial activity and environmental friendliness,and was expected to become a new type of marine antifouling coating with ideal antifouling functions.The future research directions of antifouling coatings were foreseen,aiming to provide a reference for the development of efficient,broad-spectrum and green marine antifouling coatings.
