With the inspiration of the hydrophobic properties of the fluffs of Papaver nudicaule Linn, a multiscaled superhydrophobic structure was fabricated by combining 3D printing and chemical modification. Micromorphological and hydrophobic characterization of the prepared structure were also conducted using scanning electron microscope and microforce instrument, respectively. At the macroscopic scale, the structure appears as biomimetic pillars distributed in an array on the surface of an object, while carbon nanotube clusters adhere to the pillars to form microscopic scales. Due to the multiscaled synergistic enhancement effect, the surface covered by the present structure exhibits excellent superhydrophobicity, showing the water repellency force can reach 50.68 N per square meter. Compared with hydrophobic coating and other existing preparation processes of microscopic hydrophobic structures, the method proposed is economical and simple. The multiscaled structure has strong damage resistance and stable hydrophobicity, and it is convenient for industrial production, therefore it holds applications in a diversity of fields such as directional droplet migration, fluid drag reduction and underwater gas exchange.
