从自然中学习传统上并持续提供重要的见解，以推动技术的范式转变。特别是，最近的研究表明，许多生物有机体表现出壮观的表面形貌，如形状，大小，空间组织，周期性，相互连接和层次结构，赋予它们动态适应和响应各种环境的能力。更令人兴奋的是，从更广泛的角度来看，这些通常被忽视的拓扑特征有可能从根本上改变工程表面的工作方式，例如流体如何流动，热量如何传输，以及能量如何产生，保存和转换。因此，为独特的功能设计自然启发的表面形貌将激发新的思维，并提供新的工程表面的发展范式转变。在这篇综述中，我们首先简要介绍了一些从自然界中提取的见解。然后，我们强调了最近在设计新的表面形貌方面的进展，并展示了它们在新兴领域的应用，包括热流体传输，防冰，集水，发电，粘合剂控制和软机器人。最后，我们提供了我们对这一新兴领域的看法，旨在激发对下一代新材料和设备开发的新思维，并大大扩展传统工程的界限。
Learning from nature has traditionally and continuously provided important insights to drive a paradigm shift in technology. In particular, recent studies show that many biological organisms exhibit spectacular surface topography such as shape, size, spatial organization, periodicity, interconnectivity, and hierarchy to endow them with the capability to adapt dynamically and responsively to a wide range of environments. More excitingly, in a broader perspective, these normally neglected topological features have the potential to fundamentally change the way of how engineering surface works, such as how fluid flows, how heat is transported, and how energy is generated, saved, and converted, to name a few. Thus, the design of nature-inspired surface topography for unique functions will spur new thinking and provide paradigm shift in the development of the new engineering surfaces. In this review, we first present a brief introduction to some insights extracted from nature. Then, we highlight recent progress in designing new surface topographies and demonstrate their applications in emerging areas including thermal-fluid transport, anti-icing, water harvesting, power generation, adhesive control, and soft robotics. Finally, we offer our perspectives on this emerging field, with the aim to stimulate new thinking on the development of next-generation of new materials and devices, and dramatically extend the boundaries of traditional engineering.
