| Abstract: |
| Biofouling of marine metals equipment by marine organisms in the ocean may cause many problems, including additional energy consumption, high maintenance cost, and severe corrosion damage, resulting in great loss in marine engineering. The construction of antifouling film layer on metal surface is an important way to solve the problem of marine biofouling. This paper summarizes the development process of marine anti-fouling membranes and the research status of environmentally friendly anti-fouling membranes, and focuses particularly on the new anti-fouling functional membranes and their research direction. At present, the development of new marine antifouling film on metal surface mainly focuses on two aspects:structural antifouling and functional antifouling. In terms of structural antifouling, the bionic micro-nano structure is constructed on the metal surface, and modified with low surface energy substances to form a superhydrophobic surface, which can significantly improve its ability to resist the attachment of marine organisms and achieve the purpose of green antifouling. In terms of functional antifouling, the preparation of a functional film with controllable release of antibacterial agents on the surface of metals can achieve high-efficiency antibacterial and antifouling under the premise of environmental protection, which is the future research direction. Layered double metal hydroxides (LDHs) and metal-organic frameworks (MOFs) materials have the characteristics of diverse composition choices and unique microstructures, and have antibacterial ability or the ability to load antibacterial agents, and can realize the controllable release of antibacterial agents, which are expected to become novel marine antifoulant-loading materials (carriers) with ideal antifouling performance. |
