A review of epoxy vitrimer-based thermally conductive composites

Abstract

Driven by advancements in integrated and high-power electronic devices, polymer composites featuring high thermal conductivity (TC), recyclability, and dynamic functionalization have emerged as a focal point in thermal management research. Epoxy vitrimer (EV), owing to its covalent adaptable network (CAN), which enables self-healing, recyclability, and network reconstruction, presents a novel paradigm for designing high-performance thermally conductive composites (TCCs). This review systematically reviews the synthesis strategies, exchange mechanisms, and properties of epoxy vitrimer-based thermally conductive composites (EVTCCs) across diverse CAN architectures (e.g., ester, disulfide, imine, etc.), while highlighting key advancements and future directions in this evolving field.
