仿猪笼草超滑表面及其防腐、疏热水与耐划伤性能

受猪笼草启发的光滑表面为克服当前超疏水表面的缺点(如热机械稳定性和功能耐久性)提供了另一种策略。本研究通过微纳结构构建、低表面能分子接枝和全氟聚醚(PFPE)润滑油注入制备润滑油注入光滑表面(LISS)。对其表面形貌、化学成分、润湿性、动态液体运动、自洁性、抗腐蚀性能和热机械稳定性进行了研究和分析。电化学阻抗谱(EIS)结果表明，制备的LISS即使在浸泡30天后，Rct和|Z|0.01Hz值也提高了2个数量级，具有优异的持久防腐性能。此外，LISS还具有优异的拒热水(~ 90°C水滴)和耐刮擦能力。我们相信这些结果对于理解仿生液体注入滑质材料的设计和多功能应用具有重要意义。Pitcher plant-inspired slippery surfaces offer an alternative strategy to overcome the drawbacks of current superhydrophobic surfaces, such as poor thermomechanical stability and functional durability. In this study, lubricant-infused slippery surfaces (LISS) were prepared via micro-nanostructure fabrication, low-surface-energy molecular grafting, and perfluoropolyether (PFPE) lubricant infusion. Their surface morphology, chemical composition, wettability, dynamic liquid movement, self-cleaning performance, corrosion resistance, and thermomechanical stability were systematically investigated and analyzed. Electrochemical Impedance Spectroscopy (EIS) results show that the as-prepared LISS exhibits excellent long-lasting corrosion resistance, with the charge transfer resistance (Rct) and |Z| at 0.01 Hz values increased by two orders of magnitude even after 30 days of immersion. Additionally, the LISS also demonstrates outstanding hot water repellency for ~90°C water droplets and excellent scratch resistance. We believe that these findings are of great significance for understanding the design and multifunctional applications of biomimetic liquid-infused slippery materials.
