This paper reports an easy method to imitate the "poinsettia leaves'' by constructing ZnO nanoplates on Al substrate. Using ammonium hydroxide as the reactant, together with zinc nitrate hexahydrate, randomly distributed ZnO nanoplates can be fabricated on the Al substrate directly. The morphology of the ZnO nanoplates can be controlled by the growth time, and the nanoplate growth mechanism is discussed in detail. After modification with stearic acid, the nanoplate surface shows a stable superhydrophobicity. Moreover, the superhydrophobic ZnO nanoplate surface showed much smaller corrosion current density, reduced 23,088-fold from the bare Al 6061 substrate. This facile and low-cost method may open a new avenue in the design and fabrication of superhydrophobic surfaces on Al materials with anticorrosive property.
