The origin, properties and brief introduction of Graphene

Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, forming a two-dimensional honeycomb structure. It is a basic building block of other carbon allotropes like graphite, carbon nanotubes, and fullerenes. Graphene has gained significant attention due to its remarkable properties, making it a promising material in various applications.

Origin:

Graphene was first isolated and characterized in 2004 by physicists Andre Geim and Konstantin Novoselov at the University of Manchester. They used a simple method called mechanical exfoliation or the “Scotch tape method” to peel layers of graphene from a graphite crystal.

Properties:

Strength and Flexibility: Graphene is incredibly strong and flexible. It has a tensile strength of around 130 gigapascals, making it one of the strongest known materials.

Electrical Conductivity: It exhibits exceptional electrical conductivity. Electrons in graphene move at extremely high speeds, making it an excellent conductor of electricity.

Thermal Conductivity: Graphene is an outstanding thermal conductor. It can efficiently dissipate heat, making it useful in thermal management applications.

Transparency: Despite being a single layer of atoms, graphene is transparent. It allows more than 97% of light to pass through, making it suitable for transparent conductive films and applications in electronics and optoelectronics.

Impermeability: Graphene is impermeable to gases, making it an effective barrier material. This property is useful in applications like gas sensors and packaging materials.

Biocompatibility: It is biocompatible and has potential applications in biomedical fields, such as drug delivery and imaging.
