Web2 Answers. Graphene is only transparent because it is very thin (one atom thick). If it absorbs 2% per layer then just a few hundred layers would absorb almost all light and that would still be a very thin sheet of graphite. The question should be why does graphene absorb so much light compared to diamond which really is transparent? WebMar 28, 2024 · Graphene structure contains six carbon atoms attached to each other in a hexagonal structure as shown in Figure 1.Each carbon atom establishes three covalent σ bonds and one π bond with immediate neighbors. Within the hexagonal structure there are three π bonds between the C atoms and the π electrons are delocalized over the whole …
