In actuality, the structural make-up of graphite and graphene, and the method of how to create one from the other, is slightly different. Due to graphite’s planar structure, its thermal, acoustic and electronic properties are highly anisotropic, meaning that phonons travel much more easily along the planes than they do when attempting to travel through the planes. In very basic terms graphene could be described as a single, one atom thick layer of the commonly found mineral graphite; graphite is essentially made up of hundreds of thousands of layers of graphene. . Graphene, on the other hand, is the strongest material ever recorded, more than three hundred times stronger than A36 structural steel, at 130 gigapascals, and more than forty times stronger than diamond.
