Five questions about graphene

Five questions about graphene Graphene 24 October 2018

Pioneering an innovative graphene form, Carbon Waters offers the industry an enhanced, controlled performance for its materials.

Carbon Waters is now able to produce a form of graphene that is both stable and easy to use, opening the way to numerous industrial applications.

But why is it so revolutionary? Graphene is a material unlike any other.

What is graphene made of?

Graphene is a single layer of carbon atoms, which means that it is just one atom thick.

For Alain Pénicaud, director of research at CNRS and specialist in the subject, “It is the ultimate membrane, an all-surface material.” One square meter of graphene weighs about 0.77 mg.

What are graphene’s properties?

Within this carbon “sheet,” the atoms are separated by very short bonds, on the order of 0.335 mm long.

This characteristic gives it exceptional mechanical strength: 1 mm² of graphene is able to withstand pressure of up to two tons.

It also possesses remarkable chemical inertness, making it stable where many metals start to melt or oxidize,” explains Alain Pénicaud. It is also an excellent electrical conductor.

What are graphene’s applications?

A single layer is all you need to form an impenetrable barrier that protects against moisture or gases. Graphene is starting to find applications in the industrial world as a surface barrier, in particular for corrosion resistance, but also for making an insulating material conductive.

You can create a barrier with graphene, but it would not be homogeneous; whereas a liquid containing graphene can be deposited over the entire surface that you want to protect,” adds Alain Pénicaud.

It has a wide range of applications in fields as varied as energy, aeronautics, building, and microelectronics.

How to produce graphene?

That is THE key question: how to obtain high quality graphene in sufficient quantities with a economically viable process.

Production methods using mechanical splitting or electric shocks are not transposable to large scale production.

Or do not obtain graphene of high enough quality. The graphene developed by Carbon Waters constitutes the technological answer to these production challenges.

As well as to application processes since it also produces a material that is easy to handle.

And now?

Thanks to the Carbon Waters process, it is possible to produce large quantities of graphene useful for creating homogeneous coatings.

The next stage, already well under way, involves managing industrial projects that are able to optimise the exceptional properties of graphene.

Is graphene toxic to human health?

Graphene was discovered relatively recently. While everyone agrees on its incredible properties and the possibilities it brings to industry in particular, more and more studies are also aiming to assess graphene’s toxicity on human health. This issue is attracting growing interest, including from the general public, particularly since the health crisis of 2020-2021, when graphene-based […]
