摘要
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.
