自然界生物经过长期的生物进化，必然会进化出适合生存环境的体表。天然生物表面的功能丰富而强大，具有防粘、自清洁、减阻、防冰、耐磨等特性。在应对能源危机的背景下，受自然生物表面微结构的启发，研究人员探索了减少流体阻力的仿生表面微结构，并研究了减阻机理。本文主要综述了可用于流体减阻的仿生纹理表面的研究现状，重点讨论了仿生纹理表面的微观结构形态、减阻机理以及纹理表面的制备技术。特别是，介绍了测量纹理表面减阻效果的实验方法，这是极其罕见的。最后总结了仿生表面减阻技术研究中存在的问题和未来的发展方向。该综述可为减阻在海上运输、军事武器、航空和管道系统中的实际应用和实验室研究提供参考。
After a long period of biological evolution, natural creatures will inevitably evolve body surfaces suitable for the living environment. The functions of natural biological surfaces are abundant and powerful, including antiadhesion, self‐cleaning, drag reduction, anti‐icing, wear resistance, and other characteristics. In the context of coping with the energy crisis, inspired by natural biological surface microstructures, researchers explore biomimetic surface microstructures that reduce fluid drag and investigate the mechanisms of drag reduction. Herein, mainly the current state of research on biomimetic textured surfaces that can be applied to fluid drag reduction is reviewed and the microstructures’ morphology, drag reduction mechanisms, and the fabrication techniques of textured surfaces are discussed in detail. In particular, the experimental methods for measuring the drag reduction effect of textured surfaces are introduced, which is extremely rare. The article concludes with a summary of existing problems and future directions in the research of biomimetic surface drag reduction technology. This Review can provide a reference for practical application and laboratory research of drag reduction in marine transportation, military weapons, aviation, and pipeline systems.
