To overcome instability of the lotus-inspired surfaces, slippery lubricant-infused surfaces inspired by Nepenthes pitcher plant were fabricated by the combination of fluorinated hierarchical texture and perfluoropolyether (PFPE). The hierarchical structures composed of facets, cavities, and nanoflakes were formed on the aluminum substrates by the HCl etching and the boiling water treatment. After surface fluorination, PFPE can spread over the textured aluminum surfaces via capillary effect to form continuous and homogeneous liquid films. The liquid repellency of the textured surface was demonstrated by visible experimental results and contact angle measurements. Due to the hierarchical structures that trapped enough lubricant and resisted the deformation of lubricant film, the lubricant-infused textured aluminum surface exhibited an excellent liquid repellency, low sliding angles for various liquids, and high environmental durability. Therefore, this slippery aluminum surface would be a good candidate for liquid-repellent surfaces to meet emerging needs in practical applications. 相似文献

Although slippery liquid-infused porous surfaces (SLIPSs) have been extensively studied for anticorrosion and antifouling applications, their durability and stability restrict their practicality. Herein, a technique is presented for fabricating SLIPS with dual-protection. First, a polydimethylsiloxane (PDMS) coating with a pyramidal morphology is fabricated through mold-based lithographic techniques. The mold is prepared by applying a texturing process to a monocrystalline silicon wafer of the type used to produce solar cells. Once infused with lubricant, the SLIPS is prepared and has a water-contact angle of 112°, on an inclined surface, water droplets slide easily off its surface. Due to the excellent chemical stability and low superficiality of the lubricant layer, the SLIPS offers excellent antifouling and anticorrosion properties. In a static marine environment, the SLIPS has an extremely low coverage fraction of algae. After being immersed in a 3.5% NaCl solution for 400 days, |Z|0.01 Hz ≈ 1011 Ω, and the phase angle at high frequency is approximately −90°. SLIPSs based on the PDMS coating provide dual protection (anticorrosion and antifouling), showing that this design approach produces SLIPSs with excellent potential for applications in marine environments. 相似文献
