石墨烯纤维因其体积小、柔韧性和耐磨性而成为便携式和可穿戴电子产品的有前途的候选者。在这里，我们通过两步工艺成功合成了宏观石墨烯复合纤维，即首先静电纺丝，然后化学气相沉积（CVD）。简而言之，通过静电纺丝将分散良好的 PAN 纳米纤维以带电稀液体射流喷射到铜表面。随后，CVD 生长过程使用 PAN 固体碳源和铜催化剂诱导石墨烯薄膜的形成。最后，通过在去离子水中自组装过程，由碳纳米纤维/石墨烯复合网获得皱缩和宏观的石墨烯复合纤维。温度依赖的导电行为表明石墨烯复合纤维的电子传输属于跳跃机制，典型电导率达到4.59 × 103 S m−1。这些结果表明石墨烯复合纤维有望用于下一代柔性可穿戴电子产品。
Graphene fibers are promising candidates in portable and wearable electronics due to their tiny volume, flexibility and wearability. Here, we successfully synthesized macroscopic graphene composite fibers via a two-step process, i.e. first electrospinning and then chemical vapor deposition (CVD). Briefly, the well-dispersed PAN nanofibers were sprayed onto the copper surface in an electrified thin liquid jet by electrospinning. Subsequently, CVD growth process induced the formation of graphene films using a PAN-solid source of carbon and a copper catalyst. Finally, crumpled and macroscopic graphene composite fibers were obtained from carbon nanofiber/graphene composite webs by self-assembly process in the deionized water. Temperature-dependent conduct behavior reveals that electron transport of the graphene composite fibers belongs to hopping mechanism and the typical electrical conductivity reaches 4.59 × 103 S m−1. These results demonstrated that the graphene composite fibers are promising for the next-generation flexible and wearable electronics.
