FAQs for graphene
What is graphene?
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice. First produced in 2004, when professors at England’s University of Manchester used Scotch tape to peel flakes of graphene off of graphite, the material is 200 times stronger than steel and thinner than a single sheet of paper. Graphene has many possible applications in various fields, such as batteries, sensors, solar panels, electronics, medical equipment and sports gear.
What are some good properties of graphene?
Graphene’s outstanding properties include high thermal and electrical conductivity, high elasticity and flexibility, high hardness and resistance, transparency and the ability to generate electricity via exposure to sunlight.
What is the difference between graphene and graphite?
Graphene and graphite are both allotropes of carbon, meaning they are structurally different forms of the same element. A key difference between them is that graphene is a single layer of graphite.
