Abstract
Conducting polymers are highly promising candidates for organic thermoelectrics due to their excellent processability and mechanical flexibility. Introducing self-healing mechanisms enables these materials to maintain their long-term operational stability, thereby enhancing device sustainability. This capability is crucial for wearable electronics, where thermoelectric performance frequently degrades due to accumulated mechanical damage. In this study, we developed a novel self-healing thermoelectric material to address these limitations. Specifically, a composite material was synthesized by incorporating functional components into a blended matrix of conducting and ionic polymers. Notably, the self-healing efficiency was significantly enhanced by employing a crosslinking agent to link the structurally supportive polymer with the conducting ionic polymer network. Furthermore, the unique ionic and hydration characteristics of the resulting composite further facilitated this autonomous healing process. Comprehensive characterization of the electronic and ionic thermoelectric performance confirmed a strong synergistic effect between efficient charge transport and robust self-healing properties, demonstrating the great potential of this composite material for durable, high-performance wearable device applications.
