- Abstract
The special wettability and micro/nano-structure of locust wing were investigated by a video-based contact angle (CA) meter and a scanning electron microscope (SEM). The wetting mechanism was discussed from the perspective of biological coupling. Locust wings were used as biomimetic templates to fabricate multi-functional polymer (PDMS, polydimethylsiloxane) films by soft lithography. The natural wing surface exhibits hierarchical micro/nano-structures and high adhesive superhydrophobicity, the water CA is 152°, the water sliding angle (SA) is higher than 180°. The prepared polymer film reproduces faithfully the surface microstructures of the bio-template, and displays a good hydrophobicity and high adhesion (CA 148°, SA>180°). The complex wettability of the natural and artificial locust wing surfaces ascribes to the coupling effect of material element (hydrophobic composition) and structural element (rough micro-morphology). Locust wing can be employed as a biomimetic template for design and fabrication of special functional surface.
