| Abstract: |
| Marine economy and industry play an extremely important role in the development of human society, while the fouling problem of marine organisms brings great difficulties and challenges to marine engineering and equipment. How to effectively avoid marine biological fouling has become a hot and difficult issue. At present, antifouling technologies such as mechanical antifouling, electrochemical antifouling and antifouling coatings have been applied in practice. Among them, coating antifouling technology is the most widely used. Traditional antifouling coatings made use of antifouling agents to kill marine organisms, which will cause irreversible pollution to marine ecological environment. As a result, more research is being concentrated on developing more environmentally acceptable antifouling coatings. The low surface energy antifouling coatings could eliminate marine fouling organisms without releasing hazardous compounds, owing to its lower surface energy and the shear force by water flow. Due to the environment-friendly characteristic, low surface energy marine antifouling coatings have become the focus of research in recent years. To improve the antifouling coatings with more comprehensive properties, researchers try to modify the antifouling coatings with low surface energy unceasingly. Since the starting point of marine biological pollution is the attachment and growth of bacteria, antifouling coatings with antibacterial properties could prevent marine biological pollution at the initial stage. By introducing antimicrobial agents into low surface energy coatings, antifouling coatings with composite function could be prepared to further improve the comprehensive antifouling ability of coatings. According to this background, the technical principle of marine antifouling coatings and the research status of low surface energy antifouling coatings were briefly introduced firstly in this paper, and then the technical advantages of this type of antifouling coatings were analyzed. Meanwhile, the technical shortcomings of poor static antifouling ability and weak antifouling performance to bacterial fouling organisms were proposed. These disadvantages limit the wide application of low surface energy antifouling coatings, which need to be further modified to obtain better antifouling performance. Focusing on the antibacterial composite modification of low surface energy antifouling coatings and starting with two antibacterial composite modification methods of additives and structure, the applicable types of antibacterial agents, main preparation methods and relevant research results of comprehensive antifouling properties of modified coatings were described respectively. The research on adding antibacterial agents to low surface energy antifouling coatings started early, which is relatively well developed and occupies an important position in the field of marine antifouling. By fixing organic antibacterial agent in molecular chain, the problem of precipitation loss of antibacterial agent could be solved effectively and the service life of antifouling coatings could be prolonged. At the same time, the problems of the above two kinds of antibacterial composite antifouling coatings were discussed and the corresponding solutions were put forward. For example, nanoscale metal antibacterial agent and carrier antibacterial agent could be prepared and added to antifouling coatings. Finally, the future research directions of inorganic antibacterial agents, organic antibacterial agents and natural antibacterial agents in antifouling coatings were put forward, and the development and application of antibacterial low surface energy composite marine antifouling coatings have prospected. |
