- Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb-like pattern. It is an is an allotrope of carbon. Graphene is considered to be the world’s thinnest, strongest and most conductive material – of both electricity and heat.
- Properties: It is harder than diamond yet more elastic than rubber; tougher than steel yet lighter than aluminium. Graphene is the strongest known material.
- Other Properties of Graphene are:
- Lowest resistivity substance known at room temperature.
- High thermal stability.
- High elasticity.
- High electrical conductivity.
- Electron mobility is high at room temperature.
- Graphene oxide (GO) membranes can be used to filter common salt from seawater.
Applications of graphene/GO/rGO
- Graphite and its derivate recently gained science and engineering awareness due to its numerous applications.
- The discovery of graphene is rightly regarded as a milestone in the world of material science; as can be seen in the worldwide attention, the material has received in the fields of electronics, photonics, capacitors/supercapacitors, biosensing, etc.
- They are used in numerous applications as illustrated below. In this book, applications of graphene and its derivatives are discussed in detail.
- These applications include photocatalysis, electronics, gas sensing, graphene-based heterogeneous electrodes for energy storage devices, etc. In addition, sound devices based on graphene is also explained in this book.
- Carbon Allotropes: Diamond, graphite and fullerenes (substances that include nanotubes and buckminsterfullerene) are the important allotropes of pure carbon.
- Allotropy is the property of some chemical elements to exist in two or more different forms, in the same physical state.
