聚合物材料为一些最紧迫的环境、制造和医疗挑战提供了解决方案。然而，传统的热塑性和热固性网络具有有限的重新配置和重组能力，并且无法匹配许多应用所需的动态。在聚合物网络中引入动态键合相互作用可以生产出比静态对应物更容易加工、应用和回收的材料。在这篇综述中，我们重点介绍了一系列具有动态键和可重构网络的聚合物材料，并讨论了用于实现动态行为的不同类别的分子尺度图案。在调查了控制动态网络的基本聚合物物理学之后，我们研究了许多方法来设计动态材料的时间制度以适应特定的应用。最后，我们通过讨论进一步发展和整合这些动态概念到现有的工艺和应用的聚合物材料的机会。
Polymer materials provide solutions to some of the most pressing environmental, manufacturing and health-care challenges. Traditional thermoplastic and thermoset networks, however, have a limited capacity to reconfigure and restructure, and fail to match the dynamics required for many applications. Introducing dynamic bonding interactions into polymer networks can produce materials that are more easily processed, applied and recycled than their static counterparts. In this Review, we highlight an array of polymer materials designed with dynamic bonds and reconfigurable networks, and discuss the different classes of molecular-scale motifs used to realize dynamic behaviour. After surveying the fundamental polymer physics governing dynamic networks, we examine the many ways to engineer the time regimes of dynamic materials to suit particular applications. Finally, we conclude by discussing opportunities to further develop and integrate these dynamic concepts into existing processes and applications of polymer materials.
