Tailoring and assembling graphene into functional macrostructures with well-defined configuration are key for many promising applications. We report on a graphene-based woven fabric (GWF) prepared by interlacing two sets of graphene micron-ribbons where the ribbons pass each other essentially at right angles. By using a woven copper mesh as the template, the GWF grown from chemical vapour deposition retains the network configuration of the copper mesh. Embedded into polymer matrices, it has significant flexibility and strength gains compared with CVD grown graphene films. The GWFs display both good dimensional stability in both the warp and the weft directions and the combination of film transparency and conductivity could be optimized by tuning the ribbon packing density. The GWF creates a platform to integrate a large variety of applications, e.g., composites, strain sensors and solar cells, by taking advantages of the special structure and properties of graphene.
将石墨烯剪裁并组装成具有明确结构的功能宏观结构对于许多有前途的应用至关重要。我们报告了一种基于石墨烯的编织织物（GWF）的制备方法，该织物是通过交织两组石墨烯微米带制成的，其中这些带子基本上以直角相交。通过使用编织铜网作为模板，从化学气相沉积（CVD）生长的 GWF 保留了铜网的网络结构。将其嵌入聚合物基质中，与 CVD 生长的石墨烯薄膜相比，它具有显著的柔韧性和强度提高。GWF 在经向和纬向都具有良好的尺寸稳定性，并且通过调整带材的堆积密度，可以优化薄膜的透明度和导电性的组合。GWF 通过利用石墨烯的特殊结构和性质，为集成各种应用，例如复合材料、应变传感器和太阳能电池，提供了一个平台。
