Superhydrophobic surfaces with condensed microdrops self-jumping(CMDSJ)effect on metal substrate have been developed because of their excellent application prospect in anti-frosting and dropwise condensation heat transfer.Here,we reported sprayable nanochains to structure superhydrophobic film for observation CMDSJ properties.Compared with growth process of nanorods,nanoneedles,or nanocone,there is advantage in industrialization-scale production,irregular surface treatment,and maneuverability by spray nanochains.Asfluorinated SiO2 nanochains(F-SNCs)coating could be stable deposited onto various hard or soft materials to fabricate transparent and porous superhydrophobic surfaces.The results show that condensed microdrops will coalesce and leap their original position before their sizes growing to 50 μm,and these CMDSJ properties will be maintained after multi-repetition condensation.Moreover,the CMDSJ effect did not always occur on all the superhydrophobic surfaces by contrast of the condensed parameter of different porosity.The results suggest that nanoporous structure formed by nanochains will be conducive to enhancement CMDSJ effect in superhydrophobic films,while the effect couldnt present on nanospheres surfaces with non-nanoporous structure.
