Graphene is a new material in which carbon atoms connected by sp² hybrids are closely packed into a single-layer two-dimensional honeycomb lattice structure. Its discovery won the Nobel Prize in Physics in 2010. Graphene is the thinnest, strongest and lightest material with incredible strength and elasticity.
Graphene can reach the highest level in many properties:
- Electrical conductivity is better than copper.
- Two hundred times stronger and six times lighter than steel.
- Thermal conductivity is better than any metal.
- It only absorbs 2% of light and is almost completely transparent.
- Each gram has an incredible surface area of 2500 square meters.
- Chemical components can be added to the surface to change its performance.
Uses of Graphene
Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, energy, and biomedicine. Its unique performance has improved many electronic products and batteries. Whether it is used in touch screens due to its extremely thin thickness or in supercapacitor batteries due to its high conductivity, graphene has been heavily invested by companies and research laboratories around the world. Graphene has been established as one of the most influential materials on earth.
