Electrical Conductivity through CNT’s
Uncomplicated. Ready dispersed. No agglomeration. No dust.
Carbon nanotubes (CNT) are excellent conductors which makes them valuable for a wide field of industrial applications and materials science. Their electrical properties exceed that of copper by great factors.
Future Carbon has developed and patented processes to make these properties easily accessible for the industry.
CarboDis is an extra high grate, dustfree dispersion of carbon nanotubes in water addressing various industry needs for improvement of electrical properties in their solutions.
If used e.g. for antistatic applications / coatings to safeguard against electrostatic discharge CarboDis offers permanent longevity since they don’t degrade over time as organic antistatic solutions do.
Application Simplicity 3
water based. wholly dispersed. no agglomerates.
We have developed a special, multi-stage process that allows easy utilization of CNT’s material effects. The CNT’s in CarboDis are optimally dispersed without agglomerates and the dispersion is highly stable through suitable additives or functionalization…and no surfactants.
CarboDis is water based and thus, can be easily dosed for further processing in all water based and water-compatible systems.

Energy Storage and Conversion
Li-Ion batteries are used in many applications, from consumer to industrial products. Generally they suffer from low electrical conductivities of active materials and capacity loss during cycling. CarbDis is used as an additive in the production process to improve both, rate capability and high power efficiency of such cells.
Proton exchange membrane (PEM) fuel cells are becoming increasingly prominent as an alternative source of energy for many industries e.g. automotive. For a commercial breakthrough higher power densities compared to current situation are required though.
Increase of conductivity, lifetime and gas diffusion in the gas diffusion electrode (GDE) can be achieved by using CarboDis in the production process of these layers.
For several applications, e.g. bonding, adhesives with high electrical conductivity are required. Currently adhesive properties suffer from high additive content.
CarboDis used as additive offers the opportunity to establish electrical conductivity in adhesives even at very low concentration while the adhesive properties are not negatively influenced. In some cases adhesion is even improved.
The excellent absorption behavior of CarboDis paves the way to crosslink adhesive systems. Forceless bonding of parts becomes possible by the use of microwave technology. During assembly only the adhesive heats up eliminating material stress inflicted to the parts. Cycle time is reduced down to e.g. 30 seconds only - even for larger parts!
