我们大家都有使用铅笔的经历,但几乎没有人意识到,当我们用铅笔在纸上留下字迹的同时,也不知不觉地制造出了一种新材料,这种新材料可能在不久的将来改变人类的生活,这就是目前在科学界最热门的材料——石墨烯。石墨烯与石墨有着紧密的联系。我们知道,石墨是一类层状的材料,它是由一层又一层的二维平面碳原子网络有序堆叠而形成的。由于层间的作用力较弱,因此石墨层间很容易互相剥离,形成薄的石墨片, We all had experiences of using pencils, but few realized that as we penciled the writing on the paper, we unknowingly created a new material that might not be available in the near future Future changes in human life, which is currently the most popular material in the scientific community - graphene. Graphene and graphite are closely linked. We know that graphite is a kind of layered material, which is formed by layer by layer two-dimensional planar carbon network formed by the orderly stack. Due to the weak interaction between the layers, the graphite layers are easily peeled off from each other to form a thin graphite sheet,
