Nonlinear Frameworks for Reversible and Pluripotent Wetting on Topographic Surfaces

: Soft, ultrathin frameworks nonlinearly organized in tandem are presented to realize both reversible and pluripotent wetting on topographic surfaces. A design rule is introduced by establishing and proving the theoretical model upon hierarchical textures. Nonlinear frameworks can be conformally and reversibly wet upon complex topography in nature, thereby overcoming the wetting problems in previous conventional solid systems.
