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).

MWCNTs Multi Wall Carbon Nanotubes
  • Rigid and short
  • Effective concentration of 0.5–5%
  • Can only be used to produce black conductive materials
  • Cannot be used to produce transparent conductive materials
  • Can degrade mechanical properties because of the high concentrations required
SWCNTs Single Wall Carbon Nanotubes
  • Flexible and long
  • Effective concentration from 0.01%
  • Allow the production of conductive materials of any color
  • Allow the production of transparent conductive materials
  • Preserve or improve the mechanical properties of materials

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 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 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.

As little as 0.01% TUBALL™ in a material is enough to drastically change its properties
