The lower surface of bamboo leaves was adopted as a hydrophobic surface master. Regarding the characteristics of electroforming for hydrophobic surfaces, a wet-out treatment and a cathode horizontal-rotation were adopted to improve the replication quality of micro-nano hierarchical structures. The results show that the wet-out treatment can effectively improve the nickel ion deposition in the micro-nano cavities. The cathode horizontal-rotation is proved to be helpful for the better macro-and micro-qualities of electroformed nickel mold inserts. Electroforming technology with the wet-out treatment and the cathode horizontal-rotation can significantly improve the replication quality of micro-nano hierarchical structures of bamboo leaf surfaces, and can be used to successfully fabricate the hydrophobic nickel mold inserts with high quality for further molding.
