Helical Multi Walled Carbon Nanotubes
Outside Diameter: 75–175 nm | Length: 2–15 µm
Helical Multi Walled Carbon Nanotubes (MWCNTs) are synthesized via acetylene catalytic decomposition over Ni-Cu/Al₂O₃ catalyst. Their unique helical structure, combined with high electrical conductivity and mechanical strength, makes them suitable for a wide range of advanced applications across medicine, electronics, energy, and materials science.
