Materials with switchable mechanical properties are widespread in living organisms and endow many species with traits that are essential for their survival. Many of the mechanically morphing materials systems found in nature are based on hierarchical structures, which are the basis for mechanical robustness and often also the key to responsive behavior. Many “operating principles” involve cascades of events that translate cues from the environment into changes of the overall structure and/or the connectivity of the constituting building blocks at various levels. These concepts permit dramatic property variations without significant compositional changes. Inspired by the function and the growing understanding of the operating principles at play in biological materials with the capability to change their mechanical properties, significant efforts have been made toward mimicking such architectures and functions in artificial materials. Research in this domain has rapidly grown in the last two decades and afforded many examples of bioinspired materials that are able to reversibly alter their stiffness, shape, porosity, density, or hardness upon remote stimulation. This review summarizes the state of research in this field.

具有刺激响应性机械特性的生物启发聚合物系统

具有可切换机械性能的材料广泛存在于活生物体中,赋予许多物种以其生存必不可少的特征。自然界中发现的许多机械变形材料系统都是基于分层结构,这是机械坚固性的基础,通常也是响应行为的关键。许多“操作原理”涉及一系列事件,这些事件将来自环境的线索转化为整体结构的变化和/或各个层次上组成构件的连通性。这些概念允许戏剧性的性质变化,而无需重大的成分变化。受到生物材料具有改变其机械性能的功能和对工作原理的日益了解的启发,为了模仿人造材料中的这种结构和功能,已经做出了巨大的努力。在过去的二十年中,该领域的研究迅速发展,并提供了许多受生物启发的材料的例子,这些材料能够在远程刺激下可逆地改变其刚度,形状,孔隙率,密度或硬度。这篇综述总结了该领域的研究现状。
