Research Progresses in Methods for Improving the Properties of Dynamic Covalent Polymer Networks

Macromolecular Chemistry and Physics, Journal Year: 2025, Volume and Issue: unknown

Published: March 17, 2025

Abstract Dynamic covalent polymer networks (DCPNs) are a class of cross‐linked polymeric materials with good self‐healing properties, processability, and recyclability. These generally possess dynamic bonds which can undergo reversible cleavage reformation under certain conditions. The cross‐linking nature the endows them needed mechanical strength as well processibility, effectively bridging gap between traditional thermosets thermoplastics. However, in many cases, relying on alone cannot always achieve satisfactory material so modification DCPNs has been one hot spots this area. This review summarizes recent research progress DCPNs, including introduction multiple filler blending, analyzes how modifications improve specific properties. provides comprehensive overview diverse methods to manipulate structures properties may expand their potential applications.

Dynamic Cross-Linking Chemistry Enables Advanced One-Component Thermosets

Macromolecules, Journal Year: 2024, Volume and Issue: 57(21), P. 9950 - 9959

Published: Oct. 16, 2024

This work discloses a new strategy based on dynamic cross-linking chemistry to achieve advanced one-component thermosets combining ultralong storage life and fast cross-linking. One-component containing resin cross-linker in one pot have the features of simple operation, stable quality, low waste; however, an urgently needed with long at room temperature medium–low temperatures (≤130 °C) remains enormous challenge. Herein, we innovatively propose controlled dissolution address this issue. As example, cross-linked (DCC) is synthesized via Diels–Alder reaction hide high activity commercial amine-type cross-linker. A thermoset from DCC diepoxy monomer can be stored for time rapidly below 130 °C. Moreover, also serve as latent accelerator epoxy/anhydride same control system no elevated temperatures. beneficial promoting application meeting urgent need fields composites, coatings, electronic packaging materials, automotive adhesives, etc.
