Carbon Nanotubes Doped with 50 wt% Silicon (Si) Nanopowder/Nanoparticles

Description

Carbon Nanotubes Doped with 50 wt% Silicon (Si) Nanopowder/Nanoparticles

This advanced composite material combines the exceptional electrical conductivity of multi-walled carbon nanotubes (MWCNTs) with the high surface area and semiconducting properties of silicon (Si) nanoparticles. The result is a hybrid nanomaterial engineered for applications requiring both structural reinforcement and enhanced electronic functionality.

Silicon nanoparticles, with a purity of 98.5% and an average particle size of 50 nm, provide excellent surface reactivity (85.0 m²/g) and contribute to improved charge storage and transfer in composite systems. When combined with high-purity (>97 wt%) MWCNTs—featuring excellent conductivity (>98 S/cm) and high aspect ratios—the resulting material is ideal for various high-tech applications including batteries, sensors, and nanocomposites.
