Description
Summary:[Display omitted] •Synergistic effect of structural drive and surface wetting.•Simple preparation and low cost.•High fog collection efficiency.•It is not affected by the direction of fog flow. When the direction of the fog flow changes, the fog collection efficiency of the common fog collector relying on Janus will be affected. Inspired byTillandsia and cacti, three kinds of fog collectors with different bifurcation structures that are not affected by the direction of fog flow are designed. The fog collecting efficiency of sample 3 can reach 2.26 times that of the modified cylinder, and the fog collecting efficiency is even close to 0.9 g·h−1·cm−2. In addition, the fog collecting efficiency of sample 3 can reach 12.17 times that of the unmodified cylinder. In addition, the sample can still maintain a high fog collecting level after ten fog collecting cycles.
