Abstract Finding versatile coating to prohibit three-dimensional corrosion propagation on metal surface is of essential importance. In this report, inspired by the natural pomegranate fruit, we have fabricated the partition structure by electrochemical method. The as-built Ce(OH)3 nanowall structure has circumvented the partition structure to inhibit the horizontal corrosion propagation on metal surface. Moreover, the partition structure is modified to realize superhydrophobicity and superoleophilicity wettability. Endowed by the two properties, binary-phase fluid is used to infuse the as-modified partition structure to form nano-compositing liquid infused surface (NCLIS). In vertical direction, the upgraded Nepenthes pitcher plant inspired surface has afforded much higher corrosion inhibition effect to the underneath metal substrate. After immersion for 600 h, Z0.01Hz of NCLIS is still as high as 1.19 × 108 Ω·cm2, which is ca. 2 orders of the magnitude larger than CS covered by liquid infused surface (LIS CS) with the same immersion period in seawater. Moreover, NCLIS coating shows self-healing capability to the underlying metal in atmospheric and seawater environment, even enduring the external mechanical damage. Therefore, the dual biomimetics of pomegranate and Nepenthes pitcher plant has afforded a versatile strategy to inhibit the corrosion from the horizontal and vertical directions.

纳米复合液体注入仿生隔板结构，形成仿生自愈表面，抑制腐蚀

摘要 寻找通用涂层来阻止金属表面的三维腐蚀传播至关重要。在本报告中，受天然石榴果实的启发，我们通过电化学方法制造了分区结构。建成的 Ce(OH)3 纳米壁结构绕过了分隔结构，以抑制金属表面的水平腐蚀传播。此外，对分隔结构进行了改进，以实现超疏水性和超亲油性润湿性。由于这两种特性，二相流体用于注入改性后的分配结构，形成纳米复合液体注入表面（NCLIS）。在垂直方向上，升级后的猪笼草猪笼草表面对下面的金属基材提供了更高的缓蚀效果。浸泡 600 h 后，NCLIS 的 Z0.01Hz 仍高达 1.19 × 108 Ω·cm2，约为 比在海水中浸泡时间相同的液体注入表面 (LIS CS) 覆盖的 CS 大 2 个数量级。此外，NCLIS涂层在大气和海水环境中对底层金属显示出自修复能力，甚至可以承受外部机械损伤。因此，石榴和猪笼草猪笼草的双重仿生学为抑制水平和垂直方向的腐蚀提供了一种通用策略。NCLIS涂层在大气和海水环境中对底层金属显示出自修复能力，甚至可以承受外部机械损伤。因此，石榴和猪笼草猪笼草的双重仿生学为抑制水平和垂直方向的腐蚀提供了一种通用策略。NCLIS涂层在大气和海水环境中对底层金属显示出自修复能力，甚至可以承受外部机械损伤。因此，石榴和猪笼草猪笼草的双重仿生学为抑制水平和垂直方向的腐蚀提供了一种通用策略。
