在自然界中，许多具有协同异质结构的生物软组织，如海参、骨骼肌和软骨，都表现出适应复杂环境的高功能。在人造软材料中，水凝胶因其独特的柔湿特性和弹性特性而类似于生物软组织。然而，目前的水凝胶材料缺乏必要的适应性，包括工作温度窗口窄，力学行为不可控，从而限制了其在复杂环境中的工程应用。受上述生物软组织的启发，研究人员越来越多地开发出异质结构凝胶材料，作为一种对各种力学和环境条件具有高度适应性的功能软材料。本文总结了我们最近在协同异质结构高性能自适应凝胶材料方面所做的工作，包括凝胶材料的关键设计标准和最新的制备策略。详细介绍了这些异质凝胶材料的功能适应性，包括温度适应性、润湿性、力学适应性和形状适应性。
In nature, many biological soft tissues with synergistic heterostructures, such as sea cucumbers, skeletal muscles and cartilages, exhibit high functionality to adapt to complex environments. In artificial soft materials, hydrogels are similar to biological soft tissues due to the unique integration of “soft and wet” properties and elastic characteristics. However, currently hydrogel materials lack their necessary adaptability, including narrow working temperature windows and uncontrollable mechanics, thus restrict their engineering application in complex environments. Inspired by abovementioned biological soft tissues, researchers have increasingly developed heterostructural gel materials as functional soft materials with high adaptability to various mechanical and environmental conditions. This article summarizes our recent work on high-performance adaptive gel materials with synergistic heterostructures, including the critical design criteria and the state-of-the-art fabrication strategies of our gel materials. The functional adaptation properties of these heterostructural gel materials are also presented in details, including temperature, wettability, mechanical and shape adaption.
