Abstract:

Research on dynamic covalent bonds has gained increased attention as they impart unique properties such as intrinsic healability, reprocessability, reprogramability and malleability into chemically crosslinked polymers. Combining the chemistry of dynamic covalent bonds with light-driven reactions offers exciting ways to shape functional structures along various length scales, to locally control bond exchange kinetics and/or reprogram material properties during post-processing steps. Herein, an overview of recent advances in the synthesis, processing and application of (photo)photopolymers undergoing associative bond exchange reactions is provided. Examples on thermally and light-triggered processing routes (e.g., mask lithography, imprint lithography and 3D printing) and promising (future) applications such as reversible adhesives, healable coatings and recyclable composites is given.
