A mechanically and electrically self-healing graphite composite dough for stencil-printable stretchable conductors

摘要

A composite dough composed of a liquid polymer with embedded graphite was reported, showing rapid mechanical and electrical self-healing properties under ambient conditions. The study demonstrated that the composite could be used as a highly stretchable electrical conductor with desirable characteristics, such as stable electrical restoration during repeated stretching cycles and touch-healing of disconnections.
