Not only introduction of graphene carbon nanotubes comes, but also new carbon nanomaterials and their auxiliary mechanisms\uff01 Fullerene, carbon nanotubes (CNTs, Carbon Nanotubes) and graphenes (Graphene) are popular carbon nanomaterials in recent years. Currently, five scientists have won the Nobel Prize in this field. Why are carbon nanomaterials widely sought after?
