So what is graphene and what’s so incredible about it? Will people learn to make fuel out of thin air? The most incredible thing about this material of the future is that you can even make it at home. Timestamps: What’s unique about graphene? 1:05 How graphene was discovered 1:48 How much does graphene cost 2:15 What properties does graphene have 2:41 Ways to use graphene 4:50 Is it possible to make graphene at home? 9:59 Music by Epidemic Sound https://www.epidemicsound.com/ Summary: - Graphene is not a rare or unique substance. In fact, it has the same carbon composition as the graphite rod in the pencil you write with. However, 1 mm of graphite contains about 3 million layers of graphene. - Konstantin Novoselov and Andre Geim discovered this amazing material in 2004 at the University of Manchester, where they were studying the conductivity of graphite. History claims that graphene was discovered thanks to duct tape. - At first, graphene was a very expensive material. Enough graphene to cover the head of a pin cost $ 1,100. However, by the end of 2015, 10 grams of graphene cost $ 1,000. - Graphene is an incredibly stretchy material. It can stretch up to 25% of its length. It is also very hard. In fact, it is the hardest known material - even harder than diamond. - Another unique feature of graphene is its electrical conductivity. This material conducts electricity faster and more efficiently than any other known material. - Graphene can solve the problem of water shortages in many countries. If a special filter is made from graphene, it will pass water through itself, while filtering out salt. - Even a single layer of graphene is very strong. Now imagine how strong two layers of graphene will be? Just what you need for body armor. - If manufacturers start using graphene to make smartphones, their screens will soon be able to bend in any direction, because one of the main properties of graphene is its plasticity. - Graphene can also be used in the beauty industry. It can be an excellent alternative to modern hair dyes, most of which are very harmful to hair. - Graphene can be made at home if you have enough time and patience.
