以良好控制的宏观方式大规模组装石墨烯对于实际应用是重要的。我们已经开发了一种简便和直接的方法，用于通过同轴双毛细管纺丝策略连续制造整齐的、形态限定的石墨烯基中空纤维（HF）。在高生产量的情况下，氧化石墨烯的HF和项链状HF已经被很好地控制生产，易于官能化并通过简单的热还原或化学还原转化为石墨烯HF。这项工作为大规模生产具有理想功能和形态的石墨烯基HF铺平了道路，这些功能和形态可用于流体、催化、纯化、分离和传感等领域的许多重要应用。
Large-scale assembly of graphenes in a well-controlled macroscopic fashion is important for practical applications. We have developed a facile and straightforward approach for continuous fabrication of neat, morphology-defined, graphene-based hollow fibers (HFs) via a coaxial two-capillary spinning strategy. With a high throughput, HFs and necklace-like HFs of graphene oxide have been well-controlled produced with the ease of functionalization and conversion to graphene HFs via simply thermal or chemical reduction. This work paves the way toward the mass production of graphene-based HFs with desirable functionalities and morphologies for many of important applications in fluidics, catalysis, purification, separation, and sensing.
