How To Make Graphene

TL;DR

Graphene, a single layer of carbon atoms, is the thinnest and strongest material known, with exceptional electrical and thermal conductivity.

Transcript

Picture this: you are thrown into a dingy room and told "you can't leave until you have created the thinnest material known to man." Not only that, it must also be the strongest, the best thermal conductor and as good at conducting electricity as copper. I know, it sounds hopeless. But luckily, you know something about nanotechnology. You know, rea... Read More

Questions & Answers

Q: How is graphene created?

Graphene is created by cleaving graphite using scotch tape, repeatedly folding and unfolding it until a single layer of carbon atoms remains.

Q: Why is graphene such an exceptional thermal and electrical conductor?

Graphene's perfect lattice structure allows electrons to move through it without scattering, resulting in unparalleled thermal and electrical conductivity.

Q: What are some potential applications of graphene?

Graphene has potential applications in touch screens, computers, composite materials, and solar cells due to its thinness, flexibility, strength, and conductivity.

Q: How strong is graphene compared to other materials?

Graphene is incredibly strong, as it can support the weight of an elephant placed on a pencil supported by graphene without breaking.
