This work reports a new means of preparing graphene tubes (GTs) without relying on chemical vapor deposition (CVD) and it's template-free. Surprisingly, we found that under the action of calcium oxide (CaO) and after 1500 °C heat treatment, a large amount of GTs grew on the surface of polyimide (PI). These nanotubes have a maximum diameter of about 600 nm and a length of up to millimeters, and some nanotubes even have a branching structure. We propose a simple, effective and green method which exhibits prospects for large-scale production of GTs using polymeric materials.

碳酸钙催化聚酰亚胺无模板制备石墨烯管

这项工作报告了一种不依赖化学气相沉积（CVD）且无模板的制备石墨烯管（GT）的新方法。令人惊讶的是，我们发现在氧化钙（CaO）的作用下，经过1500℃热处理后，聚酰亚胺（PI）表面生长了大量的GT。这些纳米管的最大直径约为600纳米，长度可达毫米，有些纳米管甚至具有分支结构。我们提出了一种简单、有效和绿色的方法，展示了使用聚合物材料大规模生产 GT 的前景。
