Abstract

Journal of Thermoplastic Composite Materials, Volume 39, Issue 8, Page 4607-4620, August 2026.
Thermally repairable elastomers combining high mechanical properties and efficient self-healing capability remain challenging due to the inherent property conflicts. In this work, an epoxidized natural rubber (ENR)-based vitrimer composite was ...
