Graphene nanoscrolls which could overcome the chirality dependence of metallic or semiconducting behavior in carbon nanotubes have been recently investigated and proposed for a wide variety of applications. In order to further improve their practical applications, a variety of synthetic approaches have been widely explored but with various limitations. For instance, it remains challenging to produce graphene nanoscrolls with tunable dimensions and high quantity, which greatly hinders their potential applications. Herein, we report a new and general approach to synthesize graphene nanoscrolls with accurately tunable widths and lengths at a large scale. The resulting high-quality graphene nanoscrolls show promising applications in a wide variety of electronic devices.
最近研究发现，石墨烯纳米卷可以克服碳纳米管中金属或半导体行为的手性依赖性，因此被广泛应用于各种领域。为了进一步提高它们的实际应用价值，人们广泛探索了各种合成方法，但这些方法都存在一定的局限性。例如，生产具有可调尺寸和高数量的石墨烯纳米卷仍然具有挑战性，这极大地阻碍了它们的潜在应用。在此，我们报告了一种新的通用方法，可以在大规模制备具有精确可调宽度和长度的石墨烯纳米卷。所得到的高质量石墨烯纳米卷在各种电子器件中具有广阔的应用前景。
