บท 603: The Amazing Graphene

In Jiang Chen's "Ocean Expansion" strategic plan and "Space Elevator" plan, the research of Nano material – graphene was fundamental and core.

Most people know that graphite is one of the softest substances in nature. What most people don't know, however, is that its so-called "softness" is just its macro phenomenon. For example, the hexagonal grids stacked on top of the other, the graphite interlayer structure is maintained by "the least reliable" van der Waals forces, so that the layers and layers are relatively "slippery" under the action of external force, thereby giving a "soft " illusion.

But in the direction perpendicular to the plane, graphite is "amazingly" durable!
