英文摘要 | Improving the separation efficiency and simplifying the separation process would be highly desired for oil-water separation yet still challenging. Herein, to address this challenge, we fabricated a superhydrophobic copper mesh by an immersion process and exploited it as an advanced platform for oil-water separation. To realize oil-water separation efficiently, the obtained mesh was enfolded directly to form a boat-like device, and it could also be mounted on an open end of a glass barrel to form the oil skimmer device. For these devices, they can collect the floating oils through the pores of the copper mesh while repelling water completely, and the oil collection efficiency is up to 99.5%. Oils collected in the devices can be easily sucked out into a container for storing, without requiring mechanical handing for recycling. Importantly, the miniature boat and the oil skimmer devices can retain their enhanced oil collection efficiency even after 10 cycles of oil-water separation. Moreover, exploiting its superhydrophobicity under oil, the obtained copper mesh was demonstrated as a novel platform to remove tiny water droplets from oil. |
