Graphene is an allotrope of carbon, and is a single layer thick body with the atoms arranged in a hexagonal positions on a sheet. There are as yet serious limits to the size of the sheets, and this is determined it seems by the nature of the substrate on which it is produced.
Graphene could be produce in different ways : Exfoliation, Carbon Vapor Deposition, Synthesis on Silicon Carbide. Historically, the method was to use tape on graphite, and detach the graphene layers from the tape film. Depending on your applications you can decide among different kind of graphene.
Produced by exfoliation from graphite is rather expensive - perhaps $100 000 000 per sq cm. And only in tiny pieces. Produced by carbon vapor deposition, graphene is cheaper and could be deposited on a wide range of substrates.
This field is very rapidly developing. To support the research, the European Union have in 2013 announced research grants to take graphene out of the laboratory into industry. The web site will carry news as developments are made. In the meantime, there are suppliers who are able to supply graphene on a number of substrates. A little research time will help to find the supplier that best meets your needs.

What is the lightest paper in the world made of?
The lightest paper in the world is made of graphene, which is a single layer of carbon atoms arranged in a hexagonal lattice. Graphene paper is extremely thin, lightweight, and strong, making it ideal for applications in electronics, energy storage, and advanced materials.
How does graphene form?
Graphene forms through a process called mechanical exfoliation, where layers are peeled off from graphite using adhesive tape. Another method is chemical vapor deposition, where a thin layer of graphene is grown on a metal substrate using gases like methane. Graphene can also be produced using techniques like liquid-phase exfoliation or epitaxial growth.
What are the properties of graphene?
Graphene is pretty amazing. An adequate description of the properties is rather long. There is a link below to the properties section of an article on graphene.
Where can you buy shares in graphene?
You can't buy shares in it directly, as it is not an industry-traded commodity, but you can purchase shares of companies that are aggressively investing in graphene. A clear front-runner at the moment is CVD Equipment Corporation (CVV), which, in partnership with its Columbia University-affiliate Graphene Labs, inc., is manufacturing and selling graphene products on graphene-supermarket.com. Their stock has gained precipitously, and their trading is up something like 2,228% in the last two weeks. Because there's an apparent lack of competition, coupled with gigantic demand, this company's growth potential appears very significant. It's not every day that you see a $3 stock double in value over a week, doubling again the week after that.
What is a graphene filter?
A graphene filter is a type of filter that uses graphene-based materials to capture and remove impurities from a fluid or gas. Graphene's unique properties, such as its high surface area and strength, make it an effective filtration material for applications like water purification, air filtration, and gas separation. Graphene filters are known for their efficiency, durability, and ability to remove even small particles or contaminants.
How does the conductivity of graphene compare to that of silver?
Graphene has higher conductivity than silver.
What are the key differences between graphene and graphene oxide in terms of their properties and applications?
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice, known for its exceptional strength and conductivity. Graphene oxide is graphene that has been chemically modified with oxygen-containing functional groups, making it easier to disperse in solvents. Graphene is mainly used in electronics and materials science, while graphene oxide is often used in biomedical applications due to its biocompatibility and water solubility.

What is graphene?
Graphene is a very thin layer of graphite. It is so thin, it is so close to being invisible!
Can you make your own graphene from pencils?
While it is technically possible to extract graphene from pencils using a process called exfoliation, it is not very efficient or practical for producing high-quality graphene. Laboratory techniques and equipment are typically used to produce graphene on a larger scale for commercial applications.
How can one make graphene at home?
It is not recommended to make graphene at home due to the complex and potentially dangerous process involved. Graphene is typically produced using specialized equipment and techniques in a controlled laboratory setting. Attempting to make graphene at home without proper knowledge and equipment can be hazardous.
