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.Â
- It is a two-dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb structure.Â
- 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.Â
- 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.
