A natural substance called graphene is grabbing the world’s attention. Scientists say graphene may extend computer life, boost internet speed, strengthen helmets, enhance battery charging—even make you run faster. Graphene is nearing superhero status.
Carbon is a chemical element, like oxygen or hydrogen. Batteries and coal are made of carbon. The “lead” in your pencil isn’t really made of lead. It’s carbon too. That type of carbon is known as graphite.
Graphene is a single atomic layer of graphite. Graphene atoms are bonded together in a series of hexagons. Under a microscope, graphene looks a bit like chicken wire—only so thin that it’s considered 2-D. Graphene is also extremely flexible and light weight. But don’t let its daintiness fool you. Graphene is the world’s strongest material—about 200 times stronger than steel—as well as an excellent conductor of electricity and heat.
Scientists at the University of Manchester in England first isolated graphene from graphite. They used a surprising tool for the process: cellophane tape! The researchers peeled off layers of graphite until they had a single layer left.
Just imagine what scientists could do with the strength, flexibility, light weight, thinness, and conductivity of graphene! Researchers around the world are experimenting with a variety of uses:
—Automotive: stronger, safer, more fuel-efficient car parts
—Batteries: lightweight, long-lasting, flexible cells
—Coatings: stretchable, strong, non-corrosive paint
—Electronics: bendable, lightweight, durable phones/tablet screens
—Optometry: contact lenses to help blind persons detect and translate light into electrical signals
—Security: transparent, conductive ink for tickets, ID badges, and packaging
—Water purification: membranes for filtering salt from water
Graphene has earned the title “wonder material.” And what scientists are inventing from it is amazing. Just remember that God spoke each graphene atom into existence with His command. (Hebrews 11:3) Graphene researcher Aravind Vijayaraghavan says, “As scientists, we think we are very clever and we go off and do something. We’re very proud of ourselves—only to realize that nature [God again!] beat us to it.”
And what about the promise of running faster?
Fitness brand inov-8 is experimenting with a mix of rubber and graphene to make running shoes more durable and, well, grippy. The new line should help runners stay upright (always a good idea). Folks at inov-8 say the material will “smash the limits of grip.”
According to Vijayaraghavan, the potential of graphene-infused rubber goes beyond shoes. Medical gloves and instruments, sports equipment, and protective gear could all be made stronger and lighter with graphene in the mix.
