Abstract Laser-induced graphene (LIG) is a newly-emergent processing strategy for assembling graphene-based structures and devices with low-cost, high-efficiency and high-customizability. However, with the limitation of positioning accuracy, the application of LIG for swift and continuous production of 1D graphene-fiber based electronics is still vacant. Considering the unique 1D geometry with prominent advantages for flexible and wearable devices, in this work, we adventurously proposed and investigated a vertically-oriented laser-sweeping strategy to continuously convert the ∼16.5 μm diameter polyimide monofilament into freestanding graphene fibers. Based on process-structure-property relationship modulated precisely by varied combinations of lasing power and pulse resolution, the LIG enabled fiber electronics (LIGFE) could simultaneously exhibit small diameter (

激光诱导石墨烯启用一维光纤电子

摘要 激光诱导石墨烯（LIG）是一种新兴的低成本、高效率和高定制化石墨烯基结构和器件组装工艺策略。然而，由于定位精度的限制，LIG在基于石墨烯纤维的一维电子产品的快速连续生产中的应用仍然是空缺的。考虑到独特的一维几何形状对柔性和可穿戴设备具有突出优势，在这项工作中，我们大胆地提出并研究了一种垂直定向的激光扫描策略，以将直径约 16.5 μm 的聚酰亚胺单丝连续转化为独立的石墨烯纤维。基于通过激光功率和脉冲分辨率的不同组合精确调制的工艺-结构-性能关系，
