Double-Walled Carbon Nanotubes (DWCNTs) combine the flexibility and electrical properties of single-walled CNTs with the enhanced mechanical stability of multi-walled structures. Their unique nested architecture makes them highly effective for polymer reinforcement, flexible conductive films, and transparent electrode applications. Nanographenex DWCNTs offer improved dispersion behavior and stable performance, supporting reliable integration in both research-driven development and scalable industrial processes.
