Abstract
This study investigates the effect of self-healing parameters (healing time, temperature, and pressure) on the healing efficiency of a vitrimer synthesized by crosslinking diglycidyl 1,2-cyclohexanedicarboxylate (DCN) with polyethylene imine (PEI) through a single lap-shear joint configuration. The joint strength and healing efficiency were evaluated by the lap shear test. The maximum healing efficiency reached 51.0% when the cracked lap joint was healed at 180°C for 4 h at a pressure of 5 MPa. Thermal and mechanical characterizations confirm the stability of the vitrimer up to 97°C and hence show suitability for high-performance applications in the packaging, electronics, and automotive industries. These findings provide the essential insights to improve the durability and functionality of vitrimers and contribute to sustainable self-healing material advancement.
