摘要

A robust yet healable material is fabricated

via

ring-opening metathesis polymerization (ROMP) of commercial chelating norbornenes. The dynamic metal-ligand coordination crosslinks confer high stress and Shore hardness

while enabling efficient damage recovery. This simple st

rategy offers a new paradigm for designing durable and sustainable polymeric materials.

Abstract

Thermosetting polymers exhibit outstanding mechanical properties

thermal stability

and chemical resistance due to their permanently cross-linked network structures. However

the irreversible nature of covalent cross-linking renders these materials non-reprocessable and non-recyclable

posing significant environmental challenges. Although healable polymers based on dynamic covalent bonds and supramolecular interactions have emerged as promising alternatives

a broadly applicable strategy utilizing metal-ligand coordination in thermoset systems remains underexplored. In this work

we present a robust and healable thermoset system fabricated

via

ring-opening metathesis polymerization (ROMP) of commercially available chelating norbornene comonomers. Cross-linking is accomplished through O-donor coordination to Lewis acidic metal centers

yielding polydicyclopentadiene (PDCPD)-based networks that demonstrate high mechanical strength (up to 60.8 MPa) and effective self-healing performance. This methodology offers a simple and scalable approach to developing high-performance

sustainable thermosetting materials.
