摘要

Effective treatment of frequent oil spills and endless discharged oily wastewater is crucial for the ecosystem and humanhealth. In the past two decades, the collection of oil from water surface has been widely studied through the simplefabrication of superhydrophobic meshes with various coating materials, but little attention is paid to the design aspectsof the meshes based oil-collecting device and practical oil collection. Here, 3D-printing devices with different configurationsof (super)hydrophobic meshes, circular truncated cone (CTC), cylinder and inverted CTC, and the same invertedcone-shaped structure (below the meshes for temporary oil storage) are investigated. Results demonstrate that the CTCmeshes based device especially for an oblate one not only shows higher stability and discharge of the collected oils thanprevious reports, but also allows floating oils to enter the (super)hydrophobic mesh faster. We anticipate that future successin developing high-performance (super)hydrophobic meshes and the further optimization of the CTC mesh-baseddevice parameters will make our proposed device more practical for the treatment of real-life oil spills.
