Graphene Products and Their Applications

Graphene is an allotropic form of carbon discovered in 2004, by a team of scientists from Russia and UK at Manchester University while making a successful attempt to extract a single layer of atomic sheet from a larger chunk of graphite. It is the thinnest element on the planet with strength of about 200 times that of steel.

Graphene is an allotropic form of carbon discovered in 2004, by a team of scientists from Russia and UK at Manchester University while making a successful attempt to extract a single layer of atomic sheet from a larger chunk of graphite. It is the thinnest element on the planet with strength of about 200 times that of steel. This 2 dimensional element has dense bonding of atoms structured in hexagonal cells looking like a honeycomb. This element has flexibility and is transparent in terms of light absorption. Graphene is a good conductor of electricity at normal room temperature surpassing copper. However, there are some drawbacks of using it as a conductor in place of copper.

Graphene Products

One of the grpahene products is grapheme powder. This powder does not contain a large amount of graphite impurities and grapheme oxide. It is prepared by novel 'bottom up' methodology, so that it is free from transition metals. This power is ideal for a wide range application. Graphene Dispersion is another product of graphene. It is available in aqueous as well as non-aqueous forms.

Applications of Graphene

Graphene finds usage in a number of electronic appliances and nano devices. Here are some important uses:

Transistors: The electrons in graphene atoms can traverse with a greater speed than the silicon atoms. Therefore, there is a great possibility to use this element as transistors. This nano material has superb thinness absent in any metallic element. The ballistic movement of the graphene electrons enhances the transistors to operate at higher frequencies compared to the silicon transistors.

Sensor equipments: Graphene is an excellent choice for developing sensor equipments such as gas sensors, diagnosis sensors etc. The electronic motion is relatively high in this element compared to any metallic substances making it suitable to detect the contact of any molecule with this single layer atomic material. Experiments have shown that the electronic movement is disturbed in graphene whenever it contacts other substances.

Mobile screens: The clarity of the single sheet atomic structures in graphene makes it suitable for developing advanced display screens in mobile gadgets. This is a cost effective means to reduce the production costs and market prices. Graphene is an eco friendly device good for recycling purpose.

Hydrogen storage in vehicles: Graphene sheets are useful to intensify the hydrogen molecule binding energy. Using graphene layers in fuel tank walls will enhance storage of more hydrogen fuel, largely used in cars.

Ultracapacitors: Scientific tests have revealed that developing Ultracapacitors from graphene is beneficial to store electrical energy. These capacitors are suitable for storing the same amount of charge as the Li-ion batteries and takes exceptionally reduced time to get charged.

Protection coating: Graphene layers can sustain the effects of major acids and alkaline elements. Therefore, it is possible to manufacture protection covers from this material to safeguard products having risk of damage due to such elements.

Plasma Screens: The graphene develops insulating properties upon contact with light rays. This property makes the element suitable for electronic usage. The greater transparency with absorption of mere 2.3% light waves makes it perfect to create plasma screens for new generation TV sets. This TV sets will have super clarity and excellent picture quality.
