Self-healing conductive elastomer based on double self cross-linking networks

Self-healing conductive elastomer with high mechanical strength was successfully prepared using two steps of polymerization. The existence of Polypyrrole networks could improve the self-healing capability of elastomer and endow the materials with electrical conductivity implying the potential applications in wearable devices and E-skins. A self-healing conductive elastomer with high mechanical strength and self-healing capability could be integrated into a sensor. • One double cross-linking conductive elastomer have been synthesized using one facile method. • The incorporation of PPy networks improved the conductivity and self-healing capability of the resultant hybrid elastomer. • The self-healing conductive elastomer could be used as strain-responsive sensor.
