Dynamic covalent chemistry has seen significant advancements in the past two decades. These developments are mainly focused on two aspects: the continuous discovery of new dynamic covalent bonds (DCBs) and the incorporation of various DCBs into polymer materials for different functionalities. These functional polymer materials have opened up new opportunities for sustainable development. This review provides an overview of the diverse functions enabled by DCBs in polymer materials, including self-healing, chemical recycling, and shape controlling. Key emphasis is given to three-dimensional shape reconfiguration/programming, surface patterning, and reversible actuation. Current issues, challenges, and future development directions of DCBs-containing materials are also discussed.
In the past two decades, dynamic covalent chemistry has been greatly developed, which is mainly reflected in two aspects: 1. new dynamic covalent bonds (DCBs) are continuously discovered; 2. various DCBs have been introduced into polymer materials for different functions. These functional polymer materials have brought new opportunities for sustainable development. In this review, we provide an overview of various functions endowed by DCBs in polymer materials, including self-healing, chemical recycling, and shape controlling. Particularly, we pay much attention to the three-dimensional (3D) shape reconfiguration/programming, surface patterning, and reversible actuation. In addition, we also give the current issues, challenges, and opportunities on DCBs-containing materials and point out its developing directions in the future.
