Polymers that are both elastic and self-healing are desirable for a variety of applications, but often rely on hydrogen bonding which makes them moisture-sensitive. Now, by incorporating metal–ligand interactions with different bond strengths into flexible polymer backbones, an elastomer has been devised that combines high stretchability and high dielectric strength with autonomous self-healing and mechanical actuation capabilities.
