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.
