主 题：Biomimetic Superhydrophobicity Adhesion Polymer film Locust wing
摘 要：Locust is a common flying insect. Locust wings were used as biomimetic templates to fabricate multi-functional polymer（polydimethylsiloxane, PDMS） films by soft lithography. The microstructure and wettability of the natural and artificial locust wing surfaces were investigated by means of a scanning electron microscope（SEM） and a video-based contact angle meter. The natural locust wing surface exhibits complicated hierarchical structures and high adhesive superhydrophobicity（contact angle 152°）. The prepared polymer film faithfully reproduces the surface microstructures of the bio-template, and displays a good hydrophobicity and high adhesion（contact angle 144°）. The complex wettability of the natural and artificial locust wing surfaces ascribes to the cooperative effect of hydrophobic composition and multi-dimensional rough microstructures. This work not only promotes our understanding of the wetting mechanism on bio-surfaces, but offers an inexpensive and effective approach for biomimetic fabrication of multi-functional interfacial materials.
