Carbon Nanotubes Doped with 50 wt% Iron (Fe) Nanopowder/Nanoparticles

Description

Carbon Nanotubes Doped with 50 wt% Iron (Fe) Nanopowder/Nanoparticles

This hybrid nanomaterial integrates high-purity multi-walled carbon nanotubes (MWCNTs) with 50 wt% elemental iron (Fe) nanoparticles, forming a composite with enhanced structural, electrical, and magnetic properties. The result is a high-performance material suitable for applications spanning electronics, catalysis, energy storage, and biomedical technologies.

The iron nanoparticles used in this formulation exhibit 99.99% purity, an average particle size of 800 nm, and an irregular shape with a dark grey appearance. Despite their relatively low surface area (1.0–5.0 m²/g), they deliver excellent magnetic responsiveness and mechanical reinforcement. When combined with MWCNTs—which are known for their electrical conductivity (>98 S/cm), high aspect ratio, and surface area (>65 m²/g)—this composite material offers significant performance advantages.
