Graphen is a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice. It is known for its remarkable properties, including exceptional strength, electrical conductivity, and thermal conductivity. These characteristics make it a promising material for various applications, such as electronics, energy storage, and composite materials. Discovered in 2004 by Andre Geim and Konstantin Novoselov, Graphen has sparked significant interest in the scientific community. Its unique structure allows for the development of innovative technologies, including flexible electronics and advanced batteries. Ongoing research aims to explore its potential in fields like medicine and environmental science.
