Graphene: tiny but mighty
Graphene is a completely flat single layer of carbon atoms arranged in a hexagonal lattice. Millions of layers of graphene make up the more familiar graphite, the material found in pencils. It has been studied since 1947, but for many years scientists didn’t think that its flat shape would be stable, and they were unable to isolate a single layer to test it.
They peeled flakes of graphene from graphite using ordinary sticky tape, allowing it to be tested for the first time. Upon examining the super-flat, stretchy, flexible flakes of graphene, they found that the material is (for its size) stronger than steel, harder than diamond and more conductive than copper.
Since it hit the international science scene, the material has been big news, and there are plenty of superlatives surrounding graphene to get excited about. It led to Nobel Prizes for Geim and Novoselov, huge investment, a worldwide research boom and a great deal of excitement about how it will change the world.
Wonder Materials: Graphene and Beyond will take visitors on a journey from the origin story of graphene through to the current reality of research and applications, and looks ahead to its future impact, asking how graphene might change our lives.
On every level, graphene is hard to grasp. It’s a nano-material about 1 million times thinner than a human hair. So, how do you make an exciting exhibition about something museum visitors can’t even see, let alone touch?
Well, in addition to providing an insight into the science behind graphene, we’ve also brought together the work of poets, artists and musicians that have been inspired by the material, in order to bring its story and potential to life.
Human curiosity made graphene happen. In this exhibition, we explore the idea that, much like art and poetry, science is a creative endeavour. With the help of a little imagination, we are now able to explore the full potential of this wonder material.
