Elastomers Combining Damping Efficiency With Rapid Recovery

open access: yesAdvanced Materials Technologies, EarlyView.
Double network granular elastomers (DNGEs) combine high energy dissipation under both cyclic loading and high impact with rapid shape recovery. 3D printing enables the production of complex, customizable structures with tailored performance. Recyclable DNGEs retain their properties over multiple recycling cycles.
