Electric heating behavior of flexible graphene/natural rubber conductor with self-healing conductive network

摘要: Abstract Graphene (GE)/natural rubber (NR) composites (RGE) with a conductive segregated network (RGES) are prepared by latex mixing. Results show that the RGES composite GE content of 10 phr (RGES-10) exhibits excellent electrical conductivity 2.7 S/m and good flexibility. After 4 tensile cycles subsequent thermal treatment, RGES-10 shifts to 4.4 S/m, nearly 2 times higher than unstretched samples. The increased indicates destroyed networks, which occur during process, can be healed post treatment. In addition, possesses heat propagation uniform temperature distribution. steady-state increases from 57 152 °C as applied voltage 10 20 V.
