惊艳石墨烯(Graphene)又称单层石墨片,是由一层排列在六角型(蜂巢晶格状)上的碳原子所构成的薄膜,也是当前唯一发现的二维自由态原子晶体。由于特殊的微观结构,它的柔韧性和坚固性令人难以置信:比钢铁强韧200倍,可以弯曲到很大角度而不断裂。美国工程专家杰弗雷·基萨教授曾用一种形象的方法解释石墨烯的强度:如果将一张和食品保鲜膜一样薄的石墨烯薄片覆盖在一只杯子上,然后试图用一支铅笔戳穿它,那么需
Graphene, also known as single-layer graphite sheet, is a film of carbon atoms arranged in a hexagonal (honeycomb lattice) form and is the only 2D free-state atomic crystal presently found. Due to its special microstructure, its flexibility and sturdiness are incredible: 200 times tougher than steel, it can bend to a great angle without breaking. Prof. Geoffrey Chiesa, an American engineering expert, once used a vivid method to explain the strength of graphene: If a piece of graphene foil, just as thin as a food wrap, is covered in a cup and then tried to use a pencil Puncture it, then need
