Abstract
The microstructure, wettability and chemical composition of butterfly and locust wing surfaces were investigated by a scanning electron microscope (SEM), a contact angle meter and a Fourier transform infrared spectrometer (FT-IR). The hydrophobicity models were established on the basis of Cassie equation. The wetting mechanism was comparatively discussed from the perspective of biological coupling. The butterfly and the locust wing surfaces are composed of naturally hydrophobic materials, but exhibit different complex wettability. The butterfly wing surface is of low adhesion (sliding angle 1~4ø) and superhydrophobicity (contact angle 150.5~156.2ø), while the locust wing surface is of extremely high adhesion (sliding angle>180ø) and superhydrophobicity (contact angle 150.6~154.8ø). The complex wettability of the wing surfaces ascribes to coupling effect of hydrophobic material and rough structure. The butterfly and locust wings can be used as bio-templates for design and preparation of biomedical functional surface, intelligent interfacial material and no-loss microfluidic transport channels.
