Chemical routes toward obtaining graphene materials are commonly used in the field, and one such preparation method is the unzipping of carbon nanotubes into long, thin graphene nanoribbons. In this work, we show that oxidative permanganate treatment of Scroll type multi-walled carbon nanotubes can lead to large, stacked sheets instead of nanoribbons. This difference is suggested to arise from the type of nanotube used, such as the Russian Doll form or Scroll form causing a change in the initial oxidation site location and ultimately leading to an alternate nanotube opening process.
化学途径是获得石墨烯材料的常用方法，其中一种制备方法是将碳纳米管解卷成长而薄的石墨烯纳米带。在这项工作中，我们表明，对 Scroll 型多壁碳纳米管进行高锰酸盐氧化处理会导致形成大的堆叠片，而不是纳米带。这种差异可能是由于所使用的纳米管类型引起的，例如俄罗斯套娃形式或 Scroll 形式会改变初始氧化位点的位置，并最终导致纳米管的打开过程发生变化。
