Advanced materials with high oil recycling capability plays a crucial role in rescuing marine lives from oil spill catastrophe. The existing absorption and filtration method can partially solve the challenge; however, a highly recyclable, low energy cost, and environmentally friendly method for collecting oil on open water is still missing. Herein, a novel concept, using newly developed membrane for collecting oil, with surface tension confinement and gravity is proposed. Using a 3D‐printed superhydrophobic and oleophilic membrane, this self‐floating device can selectively collect oil on water surfaces. The device can be automatically driven by a robot and achieves outstanding reusability toward oil recycling. This novel chemical concept will enable future research development of oil–water separation and oil recycling.
