Abstract

The first part of this section is introduced different preparation methods of artificial shark skin surface, including direct bio-replicated vivid shark skin, large-proportional amplification and shrunken bio-replication of shark skin, embossing forming technology and bionic composite drag reduction surface. Based on the above preparation methods, the drag reduction effects of bionic shark skin surface and composite surface of bionic shark skin are briefly discussed in the second section. It provides technical reference for the preparation of bionic surface. The third part introduced the bioinspired anti-icing surface from superhydrophobic lotus leaf and the mechanism of energy-saving dynamic anti-icing integrated with electric heating; in detail, the melting frost self-jumping phenomenon on Cassie-ice superhydrophobic surfaces and the underlying mechanism was introduced, and the ice delaying, dynamic ice adhesion reduction and energy-saving dynamic anti-icing on fiberglass cloth based superhydrophobic coatings was introduced. The results provided theoretical support for anti-icing applications of superhydrophobic coatings.
