Thermoresponsive Dynamic Covalent Single-Chain Polymer Nanoparticles Reversibly Transform into a Hydrogel

To gel and back: Polymer nanoparticles can be reversibly transformed into a chemically cross‐linked hydrogel. This transformation is triggered by the application of heat, which causes the polymer chains to aggregate, and the dynamic nature of the covalent cross‐linking serves to reorganize the polym...

Zusammenfassung:To gel and back: Polymer nanoparticles can be reversibly transformed into a chemically cross‐linked hydrogel. This transformation is triggered by the application of heat, which causes the polymer chains to aggregate, and the dynamic nature of the covalent cross‐linking serves to reorganize the polymer chains into a hydrogel network.
