Underwater facilities are often perplexed by severe and ubiquitous biofouling. The widely applied commercial antifouling materials still have several challenges in static applications. Herein, a polymer containing isoborneol and borane (PBABs), the borneol derivative structure and grafted pyridine-triphenylborane (PTPB) as antifouling groups were prepared by radical polymerization. PBABs showed high antibacterial rates for Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) of up to 95.1% and 81.1%, respectively, confirming superior antibacterial adhesion propertys. More importantly, PBABs effectively reduced the expression of mussel adhesion protein, indicating superior antifouling propertys, resulting from the synergistic effect of multiple antifouling functional groups on the material's surface. Therefore, the PBABs have been evaluated as noncytotoxic, low-cost, easily synthesized, and mass-produced, which demonstrates their great potential for actual marine applications.
水下设施常常被严重且普遍存在的生物污垢所困扰。广泛应用的商业防污材料在静态应用中仍存在一些挑战。本文通过自由基聚合制备了一种含有异冰片和硼烷（PBABs）的聚合物，其结构为冰片衍生物，并接枝了吡啶三苯基硼烷（PTPB）作为防污基团。PBABs 对大肠杆菌（E. coli）和金黄色葡萄球菌（S. aureus）的抗菌率高达 95.1%和 81.1%，证明了其具有优异的抗菌黏附性能。更重要的是，PBABs 有效降低了贻贝类黏附蛋白的表达，表现出优异的防污性能，这归因于材料表面多种防污功能基团的协同作用。因此，PBABs 被评估为具有非细胞毒性、低成本、易于合成和大规模生产的特点，这表明它们在实际海洋应用中具有巨大的潜力。
