The discovery of graphene can be traced back to 2004, which was discovered by Andre Geim and Konstantin Novoselov of Manchester University in England and Stuart Parker of the Netherlands. The professor's discovery stems from his experiments on graphite materials. The professors used a special method to tear off the graphite sheet layer by layer with adhesive tape, and finally got a very thin graphite sheet. Through the observation and study of this graphite flake, the professors found that this material has very special properties.
Graphene is a two-dimensional carbon material with only one atomic layer thickness, which is composed of carbon atoms arranged in a hexagonal lattice structure. It has some very unique properties, such as high electrical conductivity, excellent thermal conductivity, high strength and good flexibility. These characteristics make graphene a hot material in the research field, showing great potential in nanotechnology, electronics, energy storage and many other fields.
Gaim, Novoselov and Parker were awarded the 20 10 Nobel Prize in Physics for their contributions to the discovery and research of graphene. The work of professors laid the foundation for graphene research and laid a solid foundation for the future application and development of graphene.
Common uses of graphene:
1. Electronic field: Graphene is a material with excellent conductivity, which can be used to manufacture high-performance electronic devices, such as transistors, integrated circuits and sensors.
2. Material reinforcement: Graphene can be used as an additive and added to other materials to improve its mechanical properties, thermal conductivity and electrical conductivity, and can be used to manufacture high-performance composite materials.
3. Energy storage: Graphene has high specific surface area and good electrochemical performance, and can be used to manufacture energy storage and conversion equipment such as supercapacitors, lithium-ion batteries and fuel cells.
4. Photoelectric devices: Because graphene has broadband absorption and excellent photoelectric conversion efficiency, it can be used to manufacture photovoltaic devices such as solar cells, photodetectors and optical cameras.
