Through 3.7 billion years of evolution and natural selection, plants and animals in nature have ingeniously fulfilled a broad range of fascinating functions to achieve optimized performance in responding and adapting to changes in the process of interacting with complex natural environments. It is clear that the hierarchically organized micro/nanostructures of the surfaces of living organisms decisively manage fascinating and amazing functions, regardless of the chemical components of their building blocks. This conclusion now allows us to elucidate the underlying mechanisms whereby these hierarchical structures have a great impact on the properties of the bulk material. In this review, we mainly focus on advances over the last three years in bioinspired multiscale functional materials with specific wettability. Starting from selected naturally occurring surfaces, manmade bioinspired surfaces with specific wettability are introduced, with an emphasis on the cooperation between structural characteristics and macroscopic properties, including lotus leaf-inspired superhydrophobic surfaces, fish scale-inspired superhydrophilic/underwater superoleophobic surfaces, springtail-inspired superoleophobic surfaces, and Nepenthes (pitcher plant)-inspired slippery liquid-infused porous surfaces (SLIPSs), as well as other multifunctional surfaces that combine specific wettability with mechanical properties, optical properties and the unidirectional transport of liquid droplets. Afterwards, various top-down and bottom-up fabrication techniques are presented, as well as emerging cutting-edge applications. Finally, our personal perspectives and conclusions with regard to the transfer of micro- and nanostructures to engineered materials are provided.

具有特定润湿性的受生物启发的功能材料的最新进展：来自自然界和超越自然界。

经过37亿年的进化和自然选择，自然界中的动植物巧妙地履行了各种引人入胜的功能，以在响应和适应与复杂自然环境互动过程中的变化时实现优化的性能。显然，活生物体表面的层次化组织的微观/纳米结构决定性地管理着令人着迷和令人惊奇的功能，而不管其构成要素的化学成分如何。现在，该结论使我们能够阐明这些分层结构对散装材料的性能产生重大影响的潜在机制。在这篇综述中，我们主要关注过去三年中具有特定润湿性的生物启发型多尺度功能材料的进展。从选定的天然表面开始，引入具有特定润湿性的人造生物启发性表面，重点是结构特征和宏观特性之间的配合，包括荷叶启发的超疏水性表面，鱼鳞启发性的超亲水/水下超疏油性表面，弹跳的启发性超疏油性表面和猪笼草（猪笼草）启发的光滑液体注入多孔表面（SLIPSs），以及其他将特殊的润湿性与机械性能，光学性能和液滴的单向传输结合在一起的多功能表面。随后，介绍了各种自上而下和自下而上的制造技术，以及新兴的前沿应用。最后，
