Abstract

Abstract The dynamic application environments of superhydrophobic surfaces, such as in the manufacturing, chemical, and garment industries, require the fast adaptiveness of the surfaces to their surroundings. Despite the progress in materials and structural design of superhydrophobic surfaces, simultaneously achieving high superhydrophobic stability and low adhesion by traditional design is still challenging. Here, a liquid‐pressure‐guided superhydrophobic surface with self‐adjustable solid–liquid stability, and adhesion is demonstrated when reacting to the dynamic environmental requirements. To understand the underlying adaptive processes, the liquid impalement dynamics is imaged in three dimensions by confocal microscopy and the stability and superhydrophobicity are measured in varied systems. It is envisioned that the design strategy of liquid‐pressure‐guided superhydrophobic surfaces with dynamic anti‐infiltration capability can stimulate the development of stable superhydrophobicity under complex wetting conditions.
