Macro-textured superhydrophobic surfaces can reduce droplet-substrate contacttimes of impacting water droplets, however, surface designs with similarperformance for significantly more viscous liquids are missing, despite theirimportance in nature and technology such as for chemical shielding, foodstaining repellency, and supercooled (viscous) water droplet removal inanti-icing applications. Here, we introduce a deterministic, controllable andup-scalable method to fabricate superhydrophobic surfaces with a 3D-printedarchitecture, combining arrays of alternating surface protrusions andindentations. We show a more than threefold contact time reduction of impactingviscous droplets up to a fluid viscosity of 3.7mPa s, which equals 3.7 timesthe viscosity of water at room temperature, covering the viscosity of manychemicals and supercooled water. Based on the combined consideration of thefluid flow within and the simultaneous droplet dynamics above the texture, werecommend future pathways to rationally architecture such surfaces, allrealizable with the methodology presented here.
