Carbon Nanotubes Doped with 52 wt% Silica (SiO2) Nanopowder/Nanoparticles
Carbon Nanotubes doped with 52 wt% Silica nanoparticles integrate the superior electrical conductivity and mechanical resilience of CNTs with silica’s high purity, large surface area (650 m²/g), and chemical inertness. The hybrid material provides enhanced hardness, tensile strength, and elastic modulus while maintaining stability and dispersibility. Silica’s insulating and porous nature complements CNT networks, enabling multifunctional performance in electrochemical devices, coatings, and biomedical systems. CNT–SiO₂ composites are positioned as advanced materials for next-generation batteries, sensors, and structural reinforcements.
