Short Length Double-Walled Carbon Nanotubes (DWCNTs)
Purity: >65% | Outer Diameter (OD): 2–4 nm | Length: Short
Description:
Short-length Double-Walled Carbon Nanotubes (DWCNTs) consist of two concentric graphene cylinders with an outer diameter ranging from 2 to 4 nm. These nanotubes retain the unique properties of single-walled and multi-walled nanotubes, offering a balance of strength, flexibility, and conductivity. Their short length enhances their dispersibility, making them suitable for various high-performance applications in composites, energy storage, and sensors.
