Carbon Nanotubes Doped with 50 wt% Silica (SiO2) Nanopowder/Nanoparticles

Description

Carbon Nanotubes Doped with 50 wt% Silica (SiO₂) Nanopowder/Nanoparticles

Our Carbon Nanotubes Doped with 50 wt% Silica (SiO₂) Nanopowder/Nanoparticles represent a powerful hybrid nanomaterial designed to combine the unique properties of multi-walled carbon nanotubes (MWCNTs) with the functional benefits of silica nanoparticles. This synergistic composite enables enhanced electrical conductivity, thermal stability, and mechanical performance—making it ideal for use in a wide array of advanced technologies.

The material consists of high-purity (>97 wt%) MWCNTs, featuring a black color, long aspect ratio, and significant surface area (>65 m²/g). These nanotubes are uniformly doped with ultra-fine silica nanoparticles (12 nm average size) with a purity of 99.9% and a high surface area of 650 m²/g. The silica nanoparticles are near-spherical and white, contributing to improved dispersion and interface compatibility in composites and matrices.
