Carbon Nanotubes Doped with 32 wt% Silver (Ag) Nanopowder/Nanoparticles 

Carbon Nanotubes Doped with 32 wt% Silver (Ag) is a high-performance hybrid nanocomposite that expertly bridges the gap between structural reinforcement and advanced functionalization. By integrating 32 wt% silver nanoparticles into a Multi-Walled Carbon Nanotube (MWCNT) scaffold, this material achieves a stable and uniform composite that exhibits significantly enhanced hardness, tensile strength, and elasticity. The 20 nm silver particles are dispersed with high precision, ensuring excellent dispersibility and maintaining a high specific surface area. This synergy allows the exceptional electrical conductivity of the CNT network to work in tandem with silver’s unique catalytic, antimicrobial, and optical properties. Engineered for next-generation technologies, this research-grade hybrid provides a versatile platform for applications requiring a robust conductive framework coupled with superior surface reactivity and durability.

Technical Properties

Applications

• Energy Storage and Power Systems: CNT–Ag hybrids are essential components in the development of high-performance lithium-ion batteries and supercapacitors. While the carbon nanotubes provide an interconnected network of conductive pathways, the 32 wt% silver loading improves charge transfer, electrode stability, and overall cycle performance. These properties make them ideal for creating energy storage devices with higher power densities and longer operational lifespans.
• Electronics and Optoelectronic Devices: This composite is widely applied in transistors, flat panel displays, and solar cells. It effectively combines the high conductivity of CNTs with silver’s plasmonic and optical properties to enhance device efficiency, photoluminescence, and reliability. The hybrid structure also serves as an excellent material for electromagnetic interference (EMI) shielding and thermal interface materials in advanced electronic packaging.
• Biomedical Engineering and Biosensing: Leveraging the antimicrobial activity of silver and the functional surfaces of CNTs, this material is employed in sophisticated biosensors and drug delivery systems. It enables highly sensitive detection of biomolecules and provides a stable platform for nanoprobes and controlled-release diagnostics. The hybrid's biocompatibility and bioactivity make it suitable for medical device coatings and sterile clinical applications.
• High-Performance Structural Composites: Integrated into polymer, metal, and ceramic matrices, CNT–Ag hybrids act as premium reinforcement fillers. They significantly improve the hardness, tensile strength, and elastic modulus of the host material. This makes them highly suitable for aerospace, automotive, and construction applications where lightweight, multi-functional reinforcement is required to withstand mechanical stress.
• Catalysis and Environmental Remediation: Utilized as efficient catalyst supports, these hybrids leverage silver’s catalytic activity and the CNTs' conductive scaffolds for electrochemical and photocatalytic reactions. They are applied in gas-discharge tubes and industrial-scale environmental remediation to neutralize organic pollutants and monitor gas emissions. The high surface area and reactivity ensure optimized performance in complex chemical processes.
