Graphene was made by two scientists. They made it by placing the tape on graphite. Then when a layer of graphite is on the tape, they folded it until it is one atom thick. It is much stronger than steel and is also lighter and thinner than silicon. That is why many people have high expectations for it. if it is that good, why is it not used all over the world now?
It is because researchers didn’t research enough. they just started to make things out of it. When they put graphene things out on the market, everyone was disappointed. The price of the product was much more expensive, and the products didn’t significantly surpass the others. Now they are starting to research and are trying to improve.
