“…The fouling served as defect spot that accelerated condensate pinning and flooding. The corrosion and fouling could be inhibited if the surface had excellent dynamic superhydrophobicity. , Anticorrosion properties of plain copper, MPSS, NGSS, and MNSS were tested by plotting a polarization curve (Figure J). , On MNSS, nanograss on micropapillae enhanced its superhydrophobicity. Liquid–air interface with large curvature induced upward Laplace pressure (Δ P micro ) and thus made the electrolyte very difficult to penetrate the tapered gaps, which improved the impedance as well as anticorrosion and antifouling property of the surface.…”

Design of hierarchical micromorphology represents an important strategy for developing functional surfaces but has yet to be achieved for promising long-term dropwise condensation. Herein, micropapillaes overlaid with nanograss were created to enhance dropwise condensation. By analyzing the nucleation and evolution of the condensate droplets, we elucidated that these hierarchical micro-nanostructures topologized tapered gaps, which produced upward pressure, to achieve spontaneous dislodging of condensate microdroplet out of gaps, and then to trigger microdroplet navigation before finally departing from the surface by coalescence-induced jumping. The high mobility of condensate delayed flooding and contributed to a very high heat transfer coefficient of 218 kW·m–2·K–1. Moreover, these micropapillaes served as forts that protected the nanograss from being destroyed, resulting in improved mechanical and chemical robustness. Our work proposed new examples of topology creation for long-term dropwise condensation heat transfer and shed light on application integration of such promising functional surfaces.

The energy problem has been a matter of some concern worldwide over the past 20 years. On the opposite side of energy production, energy loss is another crucial problem of current energy due to the low efficiency of heat transfer from scale deposition. However, less attention has been paid on the further development of advanced antiscaling interfacial materials, which may provide promising ways to save energy by reducing scale fouling. Herein, the development of antiscaling strategies is summarized from the basic theories and fabrication methods to antiscaling interfacial materials with potential applications. First, the mechanism of scale formation and the corresponding effect on thermal conductivity are introduced. Second, the typical fabrication approaches of antiscaling interfacial materials are briefly described. Finally, the performance, potential applications, future challenges, and opportunities of the advanced antiscaling interfacial materials are comprehensively discussed.
