Graphite used in our pencil leads consists of several sheets of graphene, a single layer of carbon atoms. Like tiles in a mosaic, graphene platelets can be tessellated and form large-area transparent and conducting monolayers, which can be cost-effectively prepared by solution-processing suspensions of platelets in water or organic solvents. An individual graphene layer can be rolled-up to form carbon nanotubes, cylinders of a few nanometer diameters, which also possess excellent electrical transport properties. Large-area networks of carbon nanotubes can also be prepared by solution-processing.

我们铅笔芯中使用的石墨由几片石墨烯组成，单层碳原子。像马赛克中的瓷砖一样，石墨烯片晶可以镶嵌并形成大面积透明和导电的单层，其可以通过在水或有机溶剂中溶液处理片晶悬浮液来成本有效地制备。单个石墨烯层可以卷起形成碳纳米管，几纳米直径的圆柱体，其也具有优异的电传输特性。碳纳米管的大面积网络也可以通过溶液处理来制备。
