Description
Large Inner Diameter Thin Multi-Wall Carbon Nanotubes
Purity: >90% | Outer Diameter: 30–60 nm | Inner Diameter: 20–50 nm
These Large Inner Diameter Thin Multi-Wall Carbon Nanotubes (MWCNTs) offer a unique combination of wide internal cavity and thin graphitic walls, providing exceptional structural and functional advantages. Synthesized via alcohol pyrolysis using ferrocene as a catalyst in a floating bed reactor, this material is engineered for high electrical conductivity, surface area, and reactivity—ideal for use in nanocomposites, biomedical delivery systems, and energy-related devices.
The wide internal diameter (20–50 nm) allows for greater payload capacity in drug delivery and functionalization applications, while the outer diameter (30–60 nm) and high surface area (>200 m²/g) support excellent electrochemical and mechanical performance. With a purity above 90 wt%, these nanotubes are suitable for high-performance applications across multiple industries.
