▎ 摘　　要

A biomimetic structured graphene film (G film) with super hydrophobicity and high adhesion was successful fabricated on stainless steel (SS) surface by laser process and graphene transfer. Rose petal-like microscale structure was readily created on SS due to laser induced ablation effect. Synchronously, G film fabricated by chemical vapor deposition (CVD) demonstrated hydrophobicity due to G film lacking in hydrophilic oxygen groups. Additionally, the G film was transferred onto the surface of an etched SS (ESS), during which time, successive spinning polymethylmethacrylate (PMMA) could improve the combination of G film and the target substrate, reduce the surface folds. Moreover, the synergistic effect of rose petal-like microscale structure and the G film endowed the resultant graphene surface with unique hydrophobicity and high adhesion, which was used as a "mechanical hand" to transfer micro-droplets successfully. As a mask-free, chemical-free, and cost-effective method, the fabrication of super hydrophobic G film on SS by laser process and PMMA transfer technique may open up a new way to biomimetic graphene surfaces, and provide a novel strategy for achieving functional biomimetic surface based on petal effect.
