Samsung is developing a flexible smartphone that you can roll up like a piece of paper. This is possible thanks to a wonder called "graphene"
Graphene is a very light but very strong material made from graphite-and graphite is something we all know - it's the gray stuff in our pencils.
Graphene was discovered in 2004 it's such an amazing material that two scientists who discovered it got the noble prize for physics in 2010
Smartphone users touch their screens hundreds of times a day, so the screens have to be very strong. And smartphone must also be light, so you don't notice them in your poket. Graphene is much strong and lighter than the material we are using at the moment to make smartphone screens. It's also much, much cheaper
Samsung is not the only company that is working on projects with this attractive new material. Both nokia and IBM are looking at different uses for graphene. So let the future begin
