Born and extraordinary-the king of new materials graphene
Graphene, as the thinnest, toughest, best electrical and thermal conductivity of new nanomaterials found so far. It is a two-dimensional crystal with only one layer of atomic thickness, which is separated from graphite material and composed of carbon atoms. Known as "black gold", is the "king of new materials". Scientists even predict that graphene "will completely change the 21st century". Graphene graphitization furnace equipment
What is graphene? (high temperature graphitization furnace equipment customization)
It only takes a few seconds to charge a mobile phone? The thinnest light bulb in history? Light-driven aircraft? News about the extraordinary application of graphene continues to appear in people's vision, and it seems that graphene has become an omnipotent super material. What is graphene and what features make it highly respected?
Graphene originally exists in nature, but it is difficult to peel off a single layer structure. One layer of graphene is graphite, and graphite with a thickness of 1mm contains about 3 million layers of graphene. The pencil is gently scratched on the paper, leaving traces that may be several layers or even just one layer of graphene.
In 2004, two scientists at the University of Manchester in the United Kingdom, Andre Geim (Andre Geim) and Kestya Novoselov (Konstantin Novoselov) peeled off the graphite sheet from the highly oriented pyrolytic graphite, and then the two sides of the sheet Stick on a special tape, tear the tape, you can split the graphite sheet in two. And they kept doing this, so the sheet got thinner and thinner, and finally, they got a sheet made of only one layer of carbon atoms, which is graphene. In the following three years, Andre Gaim and Konstantin Novoselov discovered the integer quantum Hall effect and the quantum Hall effect at room temperature in the single-layer and double-layer graphene systems, respectively. For this reason, they also won the 2010 Nobel Prize in Physics.
It is hard to imagine that graphite itself is almost the softest mineral
Graphene is not only the thinnest material, but also the strongest material, breaking strength is 200 times higher than the best steel. At the same time, it has good elasticity, stretching amplitude can reach 20% of its own size. If a hammock is made of graphene with an area of 1 square meter, it can bear the weight of a cat with a weight of less than 1 milligram. Graphene graphitization furnace equipment
