Graphene Nanotubes

The only additive that can change all the materials around us, right now

What Are Graphene Nanotubes?

Graphene nanotubes, or single wall carbon nanotubes, are graphene sheets rolled into a tube. Their unique physical properties make them a universal additive that can be used in 70% of all base materials to improve their specific properties.

Despite the similarity in their names, single wall and multi wall carbon nanotubes differ in their properties and in the effects they have on materials, just like graphene (a single layer of carbon atoms) differs from graphite (multiple layers of carbon atoms).

Why Has Humankind Not Used Graphene Nanotubes Before?

Surprisingly, nanotubes – the “material of the future” and a potential driver of the new technological revolution – are not a human invention. Nanotubes are a natural phenomenon. It is not an exaggeration to say that people have always been surrounded by nanotubes.

In nature, nanotubes are formed as a result of incomplete carbon combustion. This is why the ashes of trees after forest fires might contain thousands of tonnes of nanotubes

Scientists have found traces of graphene nanotubes in Damascus steel

as well as in the ancient Chinese ink

In 1976, the Japanese scientist Morinobu Endo discovered nanotubes while doing research at the University of Orleans

Decades of research have confirmed that graphene nanotubes can be a universal additive for most of materials existing on Earth.

Nevertheless, graphene nanotubes have not been used in industry until recently because of the absence of technology for their mass production and, consequently, their high price.

In 2014 OCSiAl created the first industrial technology for synthesizing graphene nanotubes

TUBALL™ is the brand under which the first graphene nanotubes available for mass application in industry were launched on the world market.

How Exactly Does TUBALL™ Work?

TUBALL™ is the only additive where as little as 0.01% can radically change a material’s properties. But how is this possible?

When distributed in the matrix of a material, graphene nanotubes form a three-dimensional reinforcing and conductive network. This is the mechanism that enables new properties to be achieved.

It is the record length-to-diameter ratio that allows graphene nanotubes to build a 3D network at very low concentrations.

This is why TUBALL™ has a minimal effect on original color and other key properties of materials, unlike any other conductive and reinforcing additives.
