Double Walled Carbon Nanotubes

Purity: > 65%, Length: 48 µm

Double Walled Carbon Nanotubes (DWCNTs) represent a unique nanomaterial combining the stability of multi-walled structures with the high performance of single-walled tubes. Their concentric double-layer design provides enhanced mechanical strength, superior electrical conductivity, and remarkable thermal stability. This balance of robustness and functionality makes DWCNTs highly attractive for both research and industrial use. Offered with reliable purity and competitive pricing, our DWCNTs deliver consistent quality for advanced material development and innovation.
