Short Length Double Walled Carbon Nanotubes

Purity: > 65%, OD: 2-4 nm

Short Length Double Walled Carbon Nanotubes (DWCNTs, Purity >65%) are advanced nanomaterials engineered for improved dispersion and integration into functional systems. With lengths typically ranging from 0.5–2.5 µm and diameters of 2–4 nm, they combine the mechanical stability of multi-walled structures with the electronic performance of single-walled tubes. Their shortened morphology enhances processability, reduces aggregation, and enables uniform distribution in composites, electrodes, and biomedical platforms. Offered with reliable purity and competitive pricing, these DWCNTs provide consistent quality for both research and industrial innovation.

Technical Properties

Applications

• Energy and Storage Systems: Short DWCNTs provide efficient electron pathways in lithium-ion and lithium-sulfur batteries, improving conductivity and cycle stability. Their shortened length enhances dispersion in electrode matrices, making them valuable in supercapacitors and hydrogen storage systems.
• Electronics and Optoelectronics: Due to their high electrical conductivity and reduced aspect ratio, short DWCNTs are suitable for transparent conductive films, interconnects, and nanoscale transistors. They also enhance charge transport in solar cells and emission displays, supporting miniaturized device architectures.
• Composites and Mechanical Applications: Short DWCNTs disperse more uniformly in polymer and ceramic matrices compared to longer CNTs, leading to improved mechanical reinforcement without agglomeration. This makes them ideal for lightweight composites in aerospace and automotive applications.
• Chemical and Catalysis Applications: Their high surface area and shortened morphology facilitate better catalytic nanoparticle anchoring. Short DWCNTs are used in gas sensors, fuel cell electrodes, and heterogeneous catalysis, where rapid electron transfer and chemical stability are critical.
• Biomedical and Environmental Applications: Short DWCNTs are easier to functionalize and disperse in aqueous media, enabling targeted drug delivery and biosensing. Their reduced length lowers cytotoxicity risks compared to longer CNTs. They also adsorb pollutants and heavy metals, supporting environmental remediation efforts.
