Samsung is developing a flexible smartphone that you can roll up like a piece of paper.this is possible thanks to a wonder material called " graphene"
Graphene is a very light but very strong material made from graphite-and graphite is something we all know -it is the gray stuff in our pencils!
Graphene was discovered in 2004.It is such an amazing material that the two scientists who discovered it got the Nobel Prize for Physics in 2010.
Smartphone users touch their screens hundreds of times a day,so the screens have to be very strong.And smartphones must also be light,so you do not notice them in your pocket.Graphene is much stronger and lighter than the material we are using at the moment to make smartphone screens. It is 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!
