Graphene is a new type of material valued by all the countries in recent years. It has many special physical properties and has wide application prospect in military and civil fields. However, large-scale industrial production of graphene has been a worldwide problem.
Recently, the Department of Polymer Science and Technology of Zhejiang University made an important breakthrough in this respect. By using the new type of iron-based oxidant to replace the traditional oxidant, a new technique for rapid, low-cost and non-polluting graphene production is expected to solve this problem Large-scale industrial production problems. It is reported that graphene in the fields of electronics, optics and other fields is extremely broad.
Experimental data show that with the new method within 1 hour, we can make such a single layer of graphene oxide, the future is expected to be large-scale industrial applications.
Recently published an article completed by the superb research graphene research results. The result avoids many defects of the existing graphene preparation method, breaks through the traditional preparation method of graphene oxide, and finds a "green" route for low-cost preparation of single-layer graphene.
Graphene is a new type of material that countries attach importance to in recent years
Graphene is a hexagonal "honeycomb" sheet of single-layered carbon atoms. 200,000 pieces of graphene together, it is equivalent to a human hair thickness. Previously, the two-dimensional structure of carbon, which had been present in scientists' conjectures, was still hard to come by. The key challenge was how to layer graphite into extremely thin flakes.
