Learn from the nature, the undersurface of indocalamus leaf with water contact angle of 140° was taken as the mimetic object. Two template methods were chosen to fabricate polymer biomimetic surfaces which had the similar micro-nano hierarchical structure characteristics of the indocalamus leaf. The morphology and surface wettability of polymer biomimetic surfaces were investigated by scanning electron microscope and contact angle meter, respectively. The undersurface of indocalamus leaf was then used as a template. Only some replicated micro-papilla were found on the PDMS biomimetic surface fabricated by a double replica method, missing most nano-lamellar structures. The water contact angle of PDMS biomimetic surface was only increased by 7°, compared with that of PDMS flat surface. The PP biomimetic surfaces were fabricated by injection molding combined with electroforming process. Results showed that the most micro-nano hierarchical structures of indocalamus leaf were successfully transferred onto the PP surfaces. Compared with PP flat surface, the water contact angle of PP biomimetic surface was increased by 50°. The PP biomimetic surface was then modified by fluoroalkylsilane with low surface energy. Compared with PP flat surface, the water contact angle of modified PP biomimetic surface was increased by 70°, reaching 133°±2°. But the polymer biomimetic surfaces fabricated by these two template methods can not reserve the dynamic wettability of natural indocalamus leaf. Results showed that the injection molding combined with electroforming and modification by fluorochemicals could be used to fabricate biomimetic hydrophobic surfaces with high efficiency and low cost.
