Where can you buy graphene paper?

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.
