Conductive self-healing hydrogels as a fascinating class of materials have received much attention in recent years and been widely used in many fields. However, a long healing time and poor electrical conductivity have limited their extended applications. To overcome these shortcomings, we fabricated an excellent conductive self-healing hydrogel by embedding a nanocomposite of Ag nanoparticles and reduced graphene oxide (Ag/RGO) in PVA–borax dynamic networks, which exhibits a relatively high conductivity (4.43 S m⁻¹), good flexibility and excellent self-healing properties without any external stimuli. The multifunctional hydrogel could self-heal within 3 s at room temperature. It also exhibits an excellent free-shapeable property like clay such that it can be modeled into any different complex geometrical shape as desired. It is expected to have potential applications in many fields such as flexible electronic wearable devices, sensors, rechargeable batteries, and biomaterials.

具有超快自修复性能和高拉伸性能的导电且可自由变形的纳米复合水凝胶。

近年来，导电自修复水凝胶作为一类引人入胜的材料备受关注，并已广泛应用于许多领域。然而，长的愈合时间和差的电导率限制了它们的扩展应用。为了克服这些缺点，我们通过在PVA-硼砂动态网络中嵌入Ag纳米粒子和氧化石墨烯（Ag / RGO）的纳米复合材料，制成了一种导电性良好的自修复水凝胶，导电性相对较高（4.43 S m ^-1），良好的柔韧性和出色的自我修复特性，而无需任何外部刺激。多功能水凝胶可在室温下3秒内自愈。它还具有出色的自由成形特性（如粘土），因此可以根据需要将其建模为任何其他复杂的几何形状。预计它将在许多领域中具有潜在的应用，例如柔性电子可穿戴设备，传感器，可充电电池和生物材料。
