大自然总是通过模仿生物材料的结构设计或刺激响应能力来给我们制造功能材料的灵感。然而，严格的制备条件，多步骤的过程中，和高成本的方法来创建仿生系统的界面和散装限制其实际应用。因此，开发一种简单、廉价、有效的方法已成为该领域研究的重点。在这篇专题文章中，基于不同的机制，即，综述了聚合物共混物溶液的溶剂诱导相分离、共聚物胶束溶液的自组装和溶剂诱导结晶。此外，还介绍了导致独特润湿性能的特殊微观结构的研究进展。作为一种有效的仿生块体系统，在空气中的非接触电场下，开发了一种独特的快速刺激响应凝胶驱动器。通过使用这些基于非凡驱动机制的刺激响应性聚合物凝胶，可以实现具有路径控制或自主远程运动的人工肌肉。
Nature always gives us inspiration for the fabrication of functional materials by mimicking the structural design or stimuli‐responsive capability of biomaterials. However, the strict preparation conditions, multistep processes, and high cost of the methods to create biomimetic systems at the interface and in bulk limit their practical applications. Therefore, development of a simple, cheap, but effective method has become the focus of our research in this field. In this feature article, facile methods for creating lotus‐leaf‐like micro‐nano‐binary structured superhydrophobic or superamphiphobic surfaces based on different mechanisms, i.e., solvent‐induced phase separation of a polymer blend solution, self‐assembly of a copolymer micelle solution, and solvent‐induced crystallization, are summarized. Moreover, progress into the investigation on the special microstructures that induce unique wetting properties are also introduced. As an effective biomimetic bulk system, a unique swift stimuli‐responsive gel actuator has been developed under a non‐contact electronic field in air. Artificial muscles with path‐controlled or self‐governing long‐range locomotion can be realized by using these stimuli‐responsive polymer gels on the basis of the extraordinary driving mechanisms.
