Inspired by the synergistic physical\u2013chemical defense strategy of sessile marine organisms, specifically sea anemones, which combine a physical mucus barrier with antimicrobial peptide secretion, the present work develops a multi-mechanism hybrid coating\u2014designated as sea anemone-inspired fluorosilicone polyurethane\u2014that integrates low-surface-energy physical antifouling and cationic antibacterial chemical antifouling. This coating system is constructed from silicone polyurethane (PDMS-PU), a cationic antibacterial moiety (PDMS-N+), and fluorinated functional monomers. Through systematic compositional optimization, an optimal formulation (P-4) is identified, which achieves a fracture elongation of 78.19%, a normal adhesion strength of approximately 2.5 MPa, a water contact angle of 120\u00b0, and a surface energy of 12.86 mN\/m. Notably, its antibacterial rates against both Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) exceed 95%. The resultant coating uniquely synergizes low surface energy, potent antibacterial activity, excellent mechanical properties, and thermal stability, thereby enabling long-term and stable antifouling performance in static seawater environments. This work provides a crucial technological foundation for the engineering application and industrialization of green, durable marine antifouling coatings.<\/jats:p>","DOI":"10.3390\/molecules31152717","type":"journal-article","created":{"date-parts":[[2026,8,5]],"date-time":"2026-08-05T08:14:46Z","timestamp":1785917686000},"page":"2717","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Sea Anemone-Inspired Fluorosilicone Polyurethane Coating with Synergistic Low-Surface-Energy and Cationic Antibacterial Action for Static Antifouling"],"prefix":"10.3390","volume":"31","author":[{"given":"Shuiwang","family":"Jiang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuyi","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Architecture and Urban Planning, Chongqing University, Chongqing 400030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiangfeng","family":"Chen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyi","family":"Liu","sequence":"additional","affiliation":[{"name":"Dongfang Electric (Fujian) Innovation Research Institute Co., Ltd., Fuzhou 350108, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuezhi","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yahao","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui","family":"Gong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Huang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dengfeng","family":"Zeng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Marine Corrosion and Protection, Luoyang Ship Material Research Institute, Xiamen 361100, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemical and Biological Engineering, Institute of Zhejiang University-Quzhou, Zhejiang University, Hangzhou 310027, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101516","DOI":"10.1016\/j.progpolymsci.2022.101516","article-title":"Functional polymer materials for modern marine biofouling control","volume":"127","author":"Qiu","year":"2022","journal-title":"Prog.
