Graphene

Graphene Latest News

Recently, researchers developed a flexible graphene-based capacitive sensor fabricated on a paper substrate using pencil-drawn interdigitated electrodes (IDEs).

About Graphene

• It is an allotrope of carbon, along with diamond and graphite. 
• It is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure. 
• The stacked form of graphene is graphite.
• Graphene was first isolated in 2004. Since then, graphene has found hundreds of innovative applications, from sensors and electronics to energy storage and healthcare.

Properties of Graphene

• Thickness: Graphene is the world’s thinnest material – it is only one atom thick, one million times thinner than a human hair.
• Strength: It is 200 times stronger than steel but six times lighter. 
• Flexibility: It is extremely flexible and stretchable.
• Conductivity: It is an excellent electrical and thermal conductor.
• Transparency: It is almost perfectly transparent since it only absorbs 2% of light.
• It is impermeable to gases, even those as light as hydrogen or helium.
