Graphene is insoluble in water and can be mixed with polymer as antirust coating.

2. Speakers

Graphene generates sound by transmitting heat energy generated by electric current.

3. Super capacitor

Computer chips equipped with graphene supercapacitors are expected to eliminate batteries.

4. Clean up radioactive waste

The combination of graphene oxide particles and radioactive pollutants can make the removal of nuclear waste safe and cheap.

5. flexible electronics route

The first graphene integrated circuit was successfully developed by the personnel of IBM R&D company.

Silicon semiconductor chip endows computer with intelligence. It can treat the binary code that constitutes the basic unit of digital information as 1 and 0. Graphene has better conductivity than silicon. It consumes less electricity and generates less heat. Therefore, graphene is likely to process these 1 and 0 much faster than silicon.

6. Artificial muscle

When current passes through, a layer of graphene fixed on the polymer will wrinkle and stretch.

7. Explosives detection

Graphene foam can detect low-concentration explosives.

8、DNA？ sequencing

Foam filter made of graphene can be used for DNA sequencing.

9.bulletproof vest

The composite fiber of graphene and carbon nanotubes has higher strength than Kevlar fiber, which is usually used to prepare bulletproof vests.

10, night vision

A night vision photodetector with high sensitivity can be made by using a single layer of graphene as the negative and adding lead sulfide crystal to the negative.

Extended data

In 2004, Andre Geim and Konstantin Novoselov, two scientists from Manchester University, discovered that they could make graphite flakes thinner and thinner in a very simple way.

They stripped the graphite sheet from the highly oriented pyrolytic graphite, then stuck both sides of the sheet on a special tape, and tore the tape to split the graphite sheet in two. Keep going like this, the sheets are getting thinner and thinner. Finally, they got a thin sheet consisting of only one layer of carbon atoms, which is graphene.

The common methods of graphene powder production are mechanical stripping, redox and SiC epitaxial growth, and the method of thin film production is chemical vapor deposition (CVD).

Because of its excellent strength, flexibility, electrical conductivity, thermal conductivity and optical characteristics, it has made great progress in physics, material science, electronic information, computer, aerospace and other fields. Graphene, as a new nano-material with the thinnest, strongest strength and strongest electrical and thermal conductivity, is called "black gold" and is the "king of new materials".
