Abstract

Abstract: Dynamic covalent bonds (DCBs) have received significant attention over the past decade. These are covalent bonds that are capable of exchanging or switching between several molecules. Particular focus has recently been on utilizing these DCBs in polymeric materials. Introduction of DCBs into a polymer material provides it with powerful properties including self‐healing, shape‐memory properties, increased toughness, and ability to relax stresses as well as to change from one macromolecular architecture to another. This Minireview summarizes commonly used powerful DCBs formed by simple, often "click" reactions, and highlights the powerful materials that can result. Challenges and potential future developments are also discussed. Abstract : Polymeric materials containing dynamic covalent bonds, which are capable of exchanging or switching between several molecules, may display properties such as self‐healing and improved malleability, as well as stress‐relaxation and shape‐memory properties. These materials, their intriguing attributes, and potential applications are described in this Minireview.
