The antifogging properties of mosquito compound eyes (see figure) result from their elaborate superhydrophobic surface structure, which consists hexagonally non-close-packed nipples at the nanoscale and close-packed hemispheres microscale. A soft-lithography approach is adopted to fabricate artificial for exploring effects hierarchical micro- nanostructure on hydrophobicity.

Conventional understanding has it that a liquid deposited on surface tends to move along directions reduce energy, which is mainly dictated by properties rather than properties, such as tension. Achieving well-controlled directional steering remains challenging because the liquid-solid interaction occurs in two-dimensional (2D) domain. We show spreading direction of liquids with different tensions can be tailored designing 3D capillary ratchets create an asymmetric and profile both out...

Precise tuning of surface wettability – by means curvature-driven reversible switching from the pinned to roll-down superhydrophobic state (see figure) is reported for first time. The adhesion force and sliding behaviors poly(dimethylsiloxane) (PDMS) pillar arrays show strong dependence on curvature. Alteration curvature allows a water droplet be easily adjusted " pinned" "roll-down" state, which provides possibility precise, in situ control movements droplets.

Significance Condensing water droplets can be self-removed from the legs of striders in a three-step mechanism. First, migrate inside texture and grow. Then, drops are suddenly expelled out hairs, owing to elastic deformation network setae by growing drops. Ultimately, condensed leg. Self-removal condensing prevents major source risk for creature, whose hydrophobicity would reverse if were impregnated water. The design therefore provides remarkable example where conjunction hydrophobicity,...

Conductive microcables embedded in a transparent film are fabricated by inkjet printing silver-nanoparticle ink into liquid poly(dimethylsiloxane) (PDMS) precursor substrate. By controlling the spreading of droplet and rheological properties substrate, multilayer circuits composed high-resolution cables achieved using commercial printer. This facile strategy provides new avenue for highly integrated electronics.

Controlling liquid adhesion is a fundamental issue in many applications for special wettable surfaces. Compared to superhydrophobic surfaces of different water adhesion, superoleophobic controllable oil are much more practical, as it leads non-wetting both and oil.

Abstract Omniphobic fluorogel elastomers were prepared by photocuring perfluorinated acrylates and a perfluoropolyether crosslinker. By tuning either the chemical composition or temperature that control crystallinity of resulting polymer chains, broad range optical mechanical properties can be achieved. After infusing with fluorinated lubricants, fluorogels showed excellent resistance to wetting various liquids anti‐biofouling behavior, while maintaining cytocompatiblity.
