Product Description


Rhenofit® CNT-4 is a water based dispersion of single wall carbon nanotubes (SWCNT) which can be used directly for production of formulations. The dispersion is highly homogeneous and stabilized and the applied process ensures non-destructive dispersing of carbon nanotubes under mild conditions.

Possible applications include but are not limited to coatings and active material for electrodes in Li-ion batteries (LIB) as well as lead acid batteries and supercapacitors. Rhenofit® CNT-4 is especially developed for battery application and is characterized by higher capacities and charging cycles.

0.2 wt% single wall carbon nanotubes; 0.4 wt% polymer dispersing agent; 99.4 wt% water
Appearance: stable black dispersion
Odour: no odour
Compatibility: can be mixed with liquid systems and some polar organic solvents

Available Packagings:
standard packaging: 750 kg IBC. Other packagings are available on request.

What are CNTs and what are their benefits?

Carbon nanotubes (CNTs) are rolled up graphene layers which are only one atom layer thin. CNTs are only several nanometer thin, but show a length to diameter ratio of at least 150. This allows for some extraordinary properties. The pure carbon structure of CNTs results in high electrical and thermal conductivity which is at least 10 times as high as of copper. In addition, the high length to diameter ration of CNTs provides high mechanical strength (100 time stronger than steel at one sixth of the weight).

What are challenges of CNT and where does LANXESS add value?

The outstanding properties of CNTs come with a challenge: During the production process CNTs form agglomerates which prevent them from being used in industrial scale. This is exactly where LANXESS adds value. We have developed a process to exfoliate the agglomerates into single and stable CNTs. This way the CNTs unfold their full benefits in our customers’ applications.

What are LANXESS products and their application?

LANXESS has developed a broad range of aqueous CNT dispersions. This product range is called Rhenofit® CNT and offers the following advantages to our customers.

- Full utilization of CNT benefits on industrial scale
- Broad product range specifically tailored to our customers’ applications
- Global availability and technical support
- Worldwide identical quality standards
- Safe and reliable supply chain

There are many possibilities to use Rhenofit® CNT products. The most prominent areas are composites & latex, energy storage, construction & living, and coating & paints.
