AI Technical Summary

Problems solved by technology

[0002] Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is the thinnest and hardest nanomaterial known in the world. It has extraordinary electrical conductivity, thermal conductivity, strength and Excellent light transmission, can be widely used in solar cells, sensors, nanoelectronics, high-performance electronic devices, composite materials, field emission materials, gas sensors and energy storage, etc. However, problems such as low output, high cost, and poor quality of graphene seriously restrict its development and application

At present, graphene is still in the stage of research and development, pilot test, and small batch production. Industrial production has immature technology and process, and there is no intelligently controlled production line.
