Graphene is a fascinating material that has garnered widespread attention in recent years due to its unique properties, including its high surface area, electrical conductivity, and strong mechanical strength. While some have suggested that graphene might be a metal, there are several reasons why this is not necessarily the case.

One of the main criticisms of graphene as a metal is its extremely low density compared to other materials. Graphene is incredibly dense, with a mass-to-volume ratio of just 2.3 x 10^-8 g/cm^3. This makes it one of the lightest materials known, making it difficult to store or transport large quantities of it. Additionally, the very small size of individual atoms in graphene means that its electrons are more strongly bound together than those in metals, which can affect its ability to conduct electricity.
Another argument against the idea that graphene is a metal is its lack of a true metal-like crystal structure. Unlike metals, which typically have a clear, defined crystal lattice, graphene’s atomic structure is more complex and irregular. Some studies suggest that graphene may have a hybrid metallic-insulating phase, where its electrons are arranged in a way that allows them to behave both like a conductor and an insulator at the same time.
Despite these criticisms, there are still some researchers who believe that graphene could potentially be considered a metal. One reason for this belief is that some researchers have found ways to increase the density of graphene, making it more similar to a traditional metal in terms of its electronic structure. For example, researchers have been able to reduce the number of carbon atoms per unit area of graphene by a factor of up to 40, which can significantly increase its density without compromising its electrical properties.
In addition, some researchers have also studied the behavior of graphene under different conditions, such as by exposing it to intense heat or pressure. These experiments have shown that graphene can exhibit metallic behavior under certain circumstances, suggesting that it might be a promising candidate for a new class of metals.

Overall, while there are certainly valid concerns about the properties of graphene as a metal, it is unlikely that this will be the case. Instead, researchers are likely to continue to explore the potential of graphene as a material that combines the advantages of both conducting and insulating materials, such as its high electrical conductivity and strong mechanical strength. As technology continues to advance, we can expect to see many exciting applications of graphene in the future.
