Graphene powder is globally considered as being a ‘wonder material,’ owing to its impressive properties. It is also known as graphene nanopowder, due to it nano-structural behavior. It is one of the strongest and ideal conductors of heat and electricity. This immensely versatile material is finding increasingly widespread application in research and diverse industries all over the world.
About Graphene Powder
As graphene itself is ideally only one-atom-thick and formed from hexagonally connected carbon atoms. These share a single electron with three other carbon atoms which leave one electron free for adequate electrical conductivity. The Graphene powder is black in color, where the thickness is around 3-4 nanometers with the lateral dimension is 5 to 10 microns. There is 4 to 6 number of layers in the research grade graphene nanopowder. It has a high aspect ration, about 1000 times greater than the 99% of carbon.
Due to its excellent physical features, often result in graphene being called the ‘Super Carbon.’ Owing to these properties, graphene can make into different constructs and forms, such as graphene sheets, graphene powder, and graphene flakes.
- High Aspect Ration
- Easy to Handle
- Fragile exfoliated sheet
- High Purity
- Better Conductivity
- High strength
Properties of Graphene Powder
Graphene powder consists of features that are seen on a graphene sheet as well. It increasingly used in numerous electronic devices, along with several other industrial applications where efficient electrical conduction required in the high-temperature level of working conditions.
The Pi (free) electron in graphene provides excellent electrical conductivity to all forms of graphene, including graphene powder, as the movement of the particle is uninhibited across the material’s surface. The graphene material also does not require any input of energy as the lack of band gap (owing to overlapping Pi electrons) allows the electrons to move freely. The electrons can even act as photons and give the material a high level of electronic mobility.
The repetitive structure of graphene makes it an excellent material to conduct heat on its surface. The free electrons can move unobstructed over the material’s surface and allow the substance to have in-plane and inter-place thermal conductivity.
It is one of the most robust materials discovered to date. It exceeds industrial-grade steel and even diamond when it comes to tensile strength. Apart from being incredibly durable, the material is also extremely lightweight too.
- Bulk Density – 0.24 g/cc
- Thickness – 5-10 nm
- Diameter – 5 – 10 micron
- Carbon Purity – > 99%
- Surface Area – 150 sq. Meter per gram
Applications of Graphene Powder
These are the present, and potential, applications that graphene powder has in the various industries:
Sensors – Sensors are needed to detect and record even small changes in the environment. The planar form of graphene allows it to expose every atom to the surrounding, thus giving it an extremely high degree of sensitivity.
Batteries – Owing to its excellent electrical properties, graphene powder can soon replace the anode and cathode in conventional Lithium-Ion batteries that are in use today. This material is incredible when it comes to improving the life and charge capacity of the battery.
Displays – The higher level of aspect ratio and the free bond connections at either end of graphene allow excellent electron tunneling. It makes for a compelling alternative to materials that conventionally used in manufacturing touch-screen and other electronic displays.
Inks – Graphene powder is also increasingly used in printing technology. The extraordinary electrical properties of this material help to efficiently disburse graphene nanopowder into the conventional ink and help with better and improved printing technology.
