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.
