An interfacial floating tumbler with a penetrable structure and Janus wettability inspired by Pistia stratiotes

Designing advanced interfacial materials is decisive to the improvement of multiphase systems. Inspired by the superior floatability of Pistia stratiotes, here we present a superhydrophobic/hydrophilic 3D Janus floater with a water managing ability. Its self-regulated floatation mechanism, as well as its water removal logic, should provide insight into the development of multifunctional interfacial carriers in the fields of micro-devices, solar evaporation, etc.
