摘要	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, Z(0.01Hz) of NCLIS is still as high as 1.19 x 10(8) Omega.cm(2), 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.
