Abstract

This study focuses on the fabrication and evaluation of a self-repairing conductive polymer composite suitable for flexible electronic applications. The composite consists of a polyurethane matrix embedded with microcapsules filled with healing agents, enabling automatic recovery after mechanical damage. Electrical and mechanical testing demonstrated that the material could recover 92% of its original conductivity and 85% of its tensile strength over ten damage-repair cycles. Scanning electron microscopy images verified the closure of cracks and the retention of material continuity. Compared with conventional non-healing conductive films, this design significantly improves durability and operational stability. These results support the potential application of this material in wearable electronics and tactile interface devices. Future work should address long-term environmental resistance and scalable production techniques.
