Biofouling triggers extensive research in ship tribology. Antifouling technology has garnered great attention as a solution for biofouling; thus, biomimetic lubricant‐infused surfaces are developed as alternatives to superhydrophobic surfaces. In this study, we developed slippery liquid‐infused porous surfaces (SLIPS) by infusing perfluoropolyether oil into porous anodic aluminum oxide (AAO) surfaces using a vacuum impregnation device. The oil settled firmly in the AAO surfaces owing to the strong capillary forces in the pores, thus forming a lubricating layer with a low contact angle hysteresis and long‐term slippery condition. SLIPS exhibited an excellent antifouling performance by reducing 98.4% of Phaeodactylum tricornutum. The coefficient of biofilm formed by the microorganisms was also investigated. The results confirmed that the lubricating layer impeded the formation of biofilm. This research provides valuable information for the fabrication of SLIPS and its antifouling mechanism.

具有出色防污性能的5086铝合金上仿生光滑液体注入多孔表面的制备

生物污损触发了船舶摩擦学的广泛研究。作为生物污垢的解决方案，防污技术已经引起了广泛的关注。因此，仿生润滑剂注入的表面被开发为超疏水表面的替代品。在本研究中，我们通过使用真空浸渍设备将全氟聚醚油注入多孔阳极氧化铝（AAO）表面中，开发了光滑的液体注入多孔表面（SLIPS）。由于孔中强大的毛细作用力，油牢固地沉积在AAO表面，从而形成了具有低接触角滞后和长期滑爽状态的润滑层。SLIPS减少了98.4％的三角角锥菌（Phaeodactylum tricornutum），具有出色的防污性能。还研究了由微生物形成的生物膜的系数。结果证实，润滑层阻碍了生物膜的形成。该研究为SLIPS的制备及其防污机理提供了有价值的信息。
