These short length double walled carbon nanotubes (DWCNTs) from Nanografi are a black carbon nanomaterial with a purity above 65% (CAS No 308068-56-6). Each tube measures 0.5-2.5 µm in length, with an outer diameter of 2-4 nm and an inner diameter of 1-3 nm.
The double-walled structure pairs the mechanical robustness associated with multi-walled tubes with electronic behaviour closer to single-walled tubes. Because the tubes are cut short, they are easier to process, clump together less and spread evenly through composites, electrode formulations and biomedical systems.
The material offers a specific surface area of 370 m2/g and an electrical conductivity of 98 S/cm, making it suitable for both laboratory research and industrial development work. It is supplied in 5 grams, 25 grams, 100 grams, 500 grams and 1000 grams packs.
- Conductive additive in lithium-ion and lithium-sulfur battery electrodes, supercapacitors and hydrogen storage systems.
- Transparent conductive films, interconnects and nanoscale transistors, as well as charge transport layers in solar cells and emission displays.
- Uniformly dispersed reinforcement in polymer and ceramic matrices for lightweight aerospace and automotive composites.
- Support for anchoring catalytic nanoparticles in gas sensors, fuel cell electrodes and heterogeneous catalysis.
- Functionalized carriers for targeted drug delivery and biosensing, and adsorbents for pollutants and heavy metals in environmental remediation.
