Carbon nanotubes (CNTs) are cylindrical molecules of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less than 1 nanometer (nm) or multi-walled (MWCNT). Their length can reach several micrometers. Carbon nanotubes exhibit many remarkable properties including outstanding thermal and electrical conductivity and exceptional tensile strength.
To be prepared for use in applications CNTs usually first need to be dispersed into a liquid medium. This requires separation of the bundles, a process which is often carried out by sonication. However, the disadvantages of this method is that it can be very time-consuming and is only suitable for low volumes.
Carbon Nanotube production - our High Pressure Homogenizers
Our systems are much easier to scale-up - to production volumes - than other technologies.
Accelerated processing - less time consuming and resource intensive when compared to other methods.
Our technology provides an effective method to disaggregate and disperse CNT clusters with repeatable results.
Producing smaller particle sizes and CNTs of uniform size in dispersions with less potential damage to the nano-molecules.
Possible increase in CNT concentration to above 50%.
Our High Pressure Homogenizers - features
Ultra high pressures to 60,000 psi (4200 bar) and processing from Lab R&D samples to production volumes in excess of 1000 l/hour.
Sophisticated temperature control including pre- and post-cooling or heating, to help preserve product quality.
Exceptional processing versatility and systems scalability.
Easy to use, clean and service. Low on-going ownership costs.
