Hybrid conductive fillers (hybrids) are prepared through simultaneous chemical reduction of the graphene oxide and acid-treated multi-wall carbon nanotube in the presence of hydrazine. Subsequently, the thermoplastic spandex-based composite membranes with different hybrids contents are fabricated by solution casting method. At 20 wt% loading of hybrids, the membrane displays both super-stretchability (387% of elongation at break) and good electrical conductivity (49.5 S cm−1). Further investigations of the electromechanical behaviour show that the strain sensitivity is dependent on hybrids content. Therefore, the as-prepared spandex/hybrids composite membranes are promising materials for the fabrication of wearable electronics and stretchable energy storage/conversion devices.
