Carbon Nanotubes Doped with 12 wt% Silver (Ag) Nanopowder/Nanoparticles  

Carbon Nanotubes Doped with 12 wt% Silver (Ag) is a high-performance hybrid nanocomposite engineered to provide a balanced synergy between the mechanical resilience of Multi-Walled Carbon Nanotubes (MWCNTs) and the functional properties of silver nanoparticles. With a 12 wt% silver loading, this material maintains the lightweight, high-aspect-ratio framework of the CNTs while introducing critical silver-driven capabilities such as enhanced surface reactivity and improved charge transfer. The uniform dispersion of 20 nm silver particles across the CNT network significantly improves the composite's specific strength, tensile modulus, and hardness. This research-grade hybrid is specifically designed for applications where structural integrity and carbon-based conductivity are paramount, but the catalytic or antimicrobial benefits of nanosilver are required to optimize the final material performance. To preserve the purity of the silver and the structural quality of the tubes, it should be handled by professionals and stored away from direct sunlight.

Technical Properties

Applications

• Energy & Storage: In the energy sector, CNT–Ag hybrids are widely explored for supercapacitors and lithium-ion batteries. The incorporation of silver nanoparticles into the CNT matrix improves electron transfer and reduces internal resistance, which directly enhances cycle stability and energy efficiency. Beyond conventional storage, these hybrids also play a role in hydrogen storage systems, where the porous CNT framework combined with silver’s catalytic sites supports efficient adsorption and controlled release of hydrogen, making them attractive for next-generation clean energy solutions.
• Electronics & Optoelectronics: In electronics, CNT–Ag composites are used in conductive inks and printed electronics, enabling flexible circuits and RFID antennas with superior conductivity and durability. They are also integrated into transparent conductive films for solar cells and flat panel displays, serving as alternatives to indium tin oxide (ITO) due to their flexibility and cost-effectiveness. Additionally, silver’s plasmonic effects enhance the photoluminescence properties of CNTs, which is particularly valuable in sensors and optoelectronic devices where improved optical response and charge transport are critical.
• Biomedical & Healthcare: In the biomedical field, CNT–Ag hybrids are recognized for their antimicrobial properties, making them suitable for coatings in medical textiles, implants, and wound dressings. Their dual functionality allows CNTs to act as carriers while silver provides imaging contrast and antimicrobial protection, enabling advanced drug delivery systems and nanoprobes for diagnostics. Furthermore, biosensors based on CNT–Ag composites are employed for highly sensitive detection of glucose, DNA, and proteins, leveraging silver’s catalytic activity to achieve rapid and accurate biomedical measurements.
• Composites & Structural Materials: In structural applications, CNT–Ag hybrids are incorporated into polymer and ceramic composites to improve mechanical strength, hardness, and conductivity. This makes them highly relevant in aerospace and automotive industries, where lightweight yet durable materials are essential. They are also integrated into smart textiles, providing fabrics with antistatic, antimicrobial, and sensing functions, thereby opening pathways for multifunctional materials in wearable technology and advanced industrial fabrics.
• Catalysis & Environmental: In catalysis and environmental technologies, CNT–Ag hybrids serve as efficient electrocatalysts in fuel cells and photocatalytic systems, where silver nanoparticles enhance the catalytic activity of CNTs. They are also applied in water treatment systems, acting as antimicrobial and adsorptive agents for purification, ensuring cleaner and safer water supplies. Additionally, their high conductivity and stability make them suitable for gas-discharge tubes and protective devices in electronics, where reliable performance under demanding conditions is required.
