Underwater superoleophobic materials with low adhesion have been widely researched owing to their self-cleaning and anti-corrosive properties. In this study, polypyrrole (PPy) nanowire meshes have been successfully fabricated by in situ electrochemical polymerization on stainless steel mesh substrates in the presence of phosphate buffered saline as both an electrolyte and a dopant. PPy nanowire meshes have high oil contact angles (above 150°) and low sliding angles (less than 10°), and they show underwater superoleophobicity with an excellent self-cleaning performance, not only in pure water, but also in highly corrosive aqueous solutions, including salt solutions, strong acids or basic solutions. PPy nanowire meshes presented here show promise for potential applications in fields such as oil-water separation and marine oil spill clean-up.
具有低附着力的水下超疏油材料因其自清洁和抗腐蚀性能而受到广泛研究。在本研究中，通过在不锈钢网基底上原位电化学聚合，在作为电解质和掺杂剂的磷酸盐缓冲盐水存在下，成功制备了聚吡咯（PPy）纳米线网。PPy纳米线网具有高油接触角（大于150°）和低滑动角（小于10°），并且它们不仅在纯水中，而且在包括盐溶液、强酸或碱性溶液在内的高腐蚀性水溶液中都表现出具有优异自清洁性能的水下超疏油性。本文展示的PPy纳米线网在油水分离和海洋溢油清理等领域具有潜在应用前景。
