- Abstract
Interfacial floater possessing an open surface diversifies the functions of current systems in the field of solar evaporation, micro‐detector, multiphase catalysis, etc. However, most of the current floaters still face challenges such as the anti‐submersion, orientation adjusting, and multifunctional capabilities. Drawing inspiration from water striders and diving bell spiders, here a superhydrophobic cellular origami (SCO) is proposed with reliable stability, submerge resistance, switchable floatability, and multifunctional integration. The remarkable floating ability is achieved through the air storage ability of superhydrophobic air cells. SCO floats stably on the water surface and has a maximum load capacity that is 48% higher than the superhydrophobic sheet. Besides, SCO can resurface rapidly after complete submersion, even using titanium metal as substrate. To further enhance the universality of SCO, the Janus SCO with unbalanced structure can float with a specific orientation facing up and the origami structure is optimized to be switchable with hinge structure for adjustable buoyancy. To prove the concept in 3D structure, a cylindrical SCO is presented for cable locating on the water surface. This study presents an achievable strategy to extend superhydrophobic surfaces into anti‐sinking floaters, offering valuable insights into the development of multifunctional interface carriers.
