Abstract

The complex wettability, chemical composition and microstructure of locust wing surface were investigated by a video-based contact angle (CA) meter, a Fourier transform infrared spectrometer (FT-IR) and a scanning electron microscope (SEM). The wetting mechanism was discussed from the perspective of biological coupling. The locust wing possesses waxy layer and hierarchical micro-morphology. The wing surface is a natural bio-surface with superhydrophobicity (water CA 150.5~158.2ø) and high adhesion, on which the water droplet displays "Gecko state". The special wettability of the wing surface ascribes to the cooperative effect of hydrophobic material and multi-dimensional microstructure. Locust wing can be potentially used as a biomimetic template for design of complex functional surface. This work may bring interesting insights for preparation of micro-controllable superhydrophobic surface and no-loss microfluidic transport channels.
