Graphene is a single layer of graphite. It is made up of covalently bonded carbon atoms. Graphene has endless applications and will allow technologies we may not yet have imagined to be developed. A carbon allotrope, graphene was discovered in 2004 by two British scientists, Sir Andre Geim and Sir Konstantin Novosleov (who went on to win the Nobel Prize for physics for the discovery). Graphene is the material of our future. What qualities make graphene so exciting? In strength, lightness, conductivity, flexibility, and thinness are some key properties of graphene. Graphene is 300 times stronger than steel and is harder than diamonds. Graphene-based inks can be printed on clothing; graphene is bendable, light, and transparent allowing for use in wearable electronics and medical sensors. Processors for computers presently operate at approximately 2.9 GHz. When using graphene in the processors they operate at 100 GHz. Scientists have developed graphene aerogel, the lightest substance ever made. Batteries using graphene last ten times longer and recharge in a few minutes. Graphene added to paint can stop corrosion
or rusting of ships and cars. When graphene is used for the process of desalination, one of the world’s biggest problems may be solved- provision of sufficient, clean drinking water.
Discuss how our knowledge and understanding of chemical bonds has led to scientific advancements and innovation. Analyse the environmental and economic impacts of graphene.
