| Graphene's hexagonal lattice of carbon atoms.
|}

Graphene is an allotrope of carbon and at 200 times stronger than steel it is also the strongest material known to man. Microscopically, it forms a hexagonal lattice of carbon atoms with a thickness of a single atom. This means it is the first man-made material in two dimensions and is also the most thermally- and electrically-conductive material produced by man. Two-dimensional materials (2D or layered materials) have no bulk as all their atoms are at the surface.

Single-layer carbon foils were described in 1962 by Hans-Peter Boehm. However, graphene was isolated in the physics department of the University of Manchester, England in 2004 by Prof Andre Geim and Prof Kostya Novoselov. The pair won the Nobel Prize in 2010 for in Physics for their pioneering work.

Graphene was first isolated by the pair using a lump of graphite and some common sticky tape. Although the sticky-tape method is still used, it cannot be replicated on an industrial basis which means other methods must be used that can produce the material in greater quantities. For example, one of the numerous industrial methods is to ‘grow’ graphene’ on hot copper- or nickel-foil; or, when graphite is immersed in water it is exfoliated and results in an inky liquid that contains particles of graphene floating around in suspension. The ability to scale-up these methods to produce greater quantities of graphene is ongoing globally.

Graphene has remarkable properties and enormous potential of which only a fraction has yet been realised. The global market for graphene was estimated at US42.8 million in 2017 and is expected to enjoy a compound annual growth rate of around 38% up to 2025. The material is regarded as a disruptive technology that could replace existing technologies and in so doing, create new markets. It can result in numerous products and processes which stem from its remarkable properties. Typical areas of application included transport, energy, electronics, medicine, desalinisation and defence.

Graphene is flexible and therefore makes possible items such as bendable electronics – mobile phones, laptops and computer screens. Maximising the potential of graphene can be realised simply by combining it with other materials to create composite materials (i.e a combination of two or more constituent materials which result in a product that offers benefits which are greater than the sum of the two individual products).

One example formulated by researchers at the University of Manchester is a graphene and paint combination, resulting in a coating that is claimed could signal the end for rust on ships, containers and cars, and may also be applied to brick and stone for weatherproofing purposes. However, one limitation is that at the time of writing, the paint can only be made in black.

Another area is the development of membranes which can filter out harmful elements using graphene filtration. Graphene oxide membranes have highly effective separation qualities that could, for example, see carbon dioxide removed from flue gases at power stations, something that is not done on any great scale at present. Creating membranes which achieve that is a potentially enormous market.

Other applications of graphene-based composites exist in transport and aerospace industries. One possibility is a graphene-composite aircraft wing which would be much lighter than the conventional wing type and so increase an aircraft’s fuel efficiency and range. It would also mean the plane would be less prone to lightning strikes.
