The invention relates to a bionic structure with
fog collection capability, and belongs to the technical field of
fog collection. The bionic structure with the
fog collection capability aims at solving the problem of shortage of
fresh water resources existing in the prior art. The bionic structure with the
fog collection capability is of a semi-conical structure; and a plurality of grooves which are dispersed in the axial direction are formed in the outer surface of the semi-conical structure from the tip to the root, and a plurality of pits are formed in the bottom of each groove from the tipto the root. According to the bionic structure with the
fog collection capability, the semi-conical structure shape forms a
shape gradient, so that water droplets condensed on the surface of the semi-conical can move from the tip to the root under the action of
laplace pressure; and dispersed groove structures form roughness gradients on the surface of the semi-conical structure, the
surface energy of the root is enabled to be larger than that of the tip, and the movement of the water droplets from the tip to the root is promoted. In addition, the pits in the grooves form a "pinning effect",and the directional collection of the water droplets is promoted.
