The theory of graphene was first explored by P. R. Wallace in 1947 as a starting point for understanding the electronic properties of 3D graphite It is well known that graphene's history spans more than a century of chemical research. There is a vast chemical literature, of literally hundreds of papers from the early 1960s and on the topic of epitaxially grown graphene from the 1970s onwards Graphene: A Complete Chemical History Sep 20, 2019 | ACS MATERIAL LLC Graphene is a two-dimensional sheet of densely packed carbon atoms arranged in a single layer. Its structure resembles a crystal honeycomb lattice or chicken wire fence of sorts
The theory of one atomic layer graphite (Graphene) was laid out for the first time in 1947 by P. R. Wallace. The name Graphene was mentioned for the first time in 1987 . The story and research continued, but no one could make one atomic layer of Graphene, even though very complicated experiments were carried out . • Early: Thlheoretical description • 1962: Named by Hanns‐Peter Boehm (Graphite + ‐ene) • 2004: Single‐atom‐thick, free‐standing graphene is extracted (by Andre Geim and Konstantin Novoselov, Manchester University, U.K.) • 2005: Anomalous quantum Hall effect was observed • 2010:. The History of Graphene Although the existence of graphene had been theorized long before it was finally produced in a lab, it was physically isolated for the first time in 2004 by Russian scientists Andre Geim and Konstantin Novoselov while working at the University of Manchester Graphene was first discussed in 1946, by Canadian physicist Philip Russel Wallace. Wallace didn't believe it was possible to make graphene; what he was interested in studying was graphite, the stuff in pencil lead
Graphene (Fig. 1) is a hexagonal structure consisting of sp 2 hybridized carbon atoms, described by some as the 'mother' of all graphitic carbon materials due to it essentially being the building block for carbon nanotubes (effectively 'rolled up' graphene sheets) and graphite (stacked graphene sheets held together by strong Van der Waal's forces) . English chemist Benjamin Collins Brodie recognized the highly layered nature of thermally reduced graphite oxide as early as 1859 having reported the atomic weight of graphite in the Philosophical Transactions of the Royal Society of London that year
