动态材料（DM）或动力学在材料科学的广泛挑战中具有潜在的应用。这些应用包括作为循环塑料经济一部分的可持续材料、具有定制高应力特性的先进材料和生物医学试剂。DM由通过可逆共价和非共价连接基团交联的聚合物组成。该基团提供可逆键，其赋予材料诸如（再）愈合、适应性、韧性的性质。连接体的性质决定了动力剂的稳定性和动力学性质，尽管对于许多应用，单独的连接体不能提供具有复杂多响应功能的材料。多个动态连接子的组合可以将互补功能引入到单一材料中。这种连接体的组合通过匹配它们的优点并抵消缺点，或者通过选择用于特定功能的连接体，例如一个连接体用于快速交换，另一个连接体响应外部刺激，来增强集体材料特性。这一贡献突出的可能性和独特的功能，包含多个动态连接器的材料，审查具有多个动态键的材料和应用程序的基本发现促进了多个连接基团化学的存在。
Dynamic materials (DMs) or dynamers have potential applications across a broad range of material science challenges. These applications include sustainable materials as a part of the circular plastics economy, advanced materials with tailored high stress properties and biomedical agents. DMs are comprised of polymers that crosslinked through reversible covalent and noncovalent linking groups. This group provides reversible bonds, which impart properties such as (re)healing, adaptability, toughness into a material. The nature of the linker dictates the dynamer's stability and dynamic properties, although for many applications one linker alone cannot give materials with complex multiresponsive functions. The combination of multiple dynamic linkers can introduce complementary functionalities into a single material. This combination of linkers enhances the collective material properties by matching their strengths and offsetting the weaknesses, or by selecting linkers for specific functions, such as one linker for rapid exchange and the other to respond to external stimuli. This contribution highlights the possibilities and unique features of materials containing multiple dynamic linkers, reviewing both fundamental discoveries of materials possessing multiple dynamic bonds and applications facilitated by the presence of multiple linking group chemistry.
