Carbon Nanotubes Doped with 52 wt% Alumina (Al2O3) Nanopowder/Nanoparticles

Carbon Nanotubes doped with 52 wt% Alumina (Al₂O₃) nanoparticles combine the superior electrical conductivity and mechanical resilience of CNTs with the thermal stability, chemical resistance, and hardness of alumina. This hybrid material delivers significant improvements in tensile strength, elastic modulus, and durability while maintaining high purity and stability. The synergy between conductive CNT networks and ceramic Al₂O₃ particles makes this composite ideal for advanced applications requiring both electrical performance and structural reinforcement. With its versatility, CNT–Al₂O₃ hybrids are positioned as high-value solutions for energy storage, electronics, biomedical systems, and composite engineering.
