摘要：

In the present work, orienting to practicality and functionality beyond original fundamental simulation, we succeeded in fabricating superamphiphobic surfaces, which are super-repellent both to water and oil, upon common engineering metals (zinc, aluminum, iron, and nickel) and their alloys (Zn-Fe alloy and brass) by taking advantage of an electrochemical reaction in perfluorocarboxylic acid solutions. Via control over the chain length, concentration of perfluorocarboxylic acid, and the process time, textured rough structures on different substrates were achieved. The prepared surfaces show superamphiphobicity due to the synergistic effect of their special surface compositions and microscopic structures.
