Graphene is a material made of carbon, but only as thick as one atom — a sheet so thin you cannot see it as a layer with your eyes. That sheet is very strong for how light it is, and electricity moves through it well, so scientists talk about it for future phones, batteries, and screens. Though actually, you have already met it in a way: the grey-black stuff in a pencil is graphite, and graphite is lots of these sheets stacked like pages in a book. Graphene is one single page. It is a lab and news word, not a kitchen word. People sometimes say graphene when they only mean “some new carbon stuff,” a little loosely.
組成From graph(ite) + -ene, a chemistry ending. So: the carbon in pencils, named as one ultra-thin sheet.

graphenenoun/ˈɡɹæf.iːn/
- 1
chemistrynatural-sciencesorganic-chemistryAny polycyclic aromatic hydrocarbon having the structure of part of a layer of graphite.

chemistryinorganic-chemistrynatural-sciencesAn arbitrarily large-scale, one-atom-thick layer of graphite, an allotrope of carbon, that has remarkable electric characteristics.
- Graphene is the strongest, thinnest material known to exist. A form of carbon, it can conduct electricity and heat better than anything else. And get ready for this: It is not only the hardest material in the world but also one of the most pliable. Only a single atom thick, it has been called the wonder material. Graphene could change the electronics industry, ushering in flexible devices, supercharged quantum computers, electronic clothing and computers that can interface with the cells in your body.
- As a microbullet impacts the graphene, the diameter of the cone it creates – determined by later examination of the petals – provides a way to measure how much energy the graphene absorbs before breaking.
