Carbon Nanotubes Doped with 52 wt% Silver (Ag) Nanopowder/Nanoparticles 

Carbon Nanotubes Doped with 52 wt% Silver (Ag) is an advanced hybrid nanocomposite that integrates the extraordinary mechanical and electrical properties of Multi-Walled Carbon Nanotubes (MWCNTs) with the superior conductivity and bioactivity of silver nanoparticles. This synergistic combination overcomes the limitations of individual components; the CNT scaffold prevents silver nanoparticles from agglomerating, while the 52 wt% silver loading creates a highly conductive network across the carbon matrix. Characterized by a high specific surface area and exceptional tensile strength, this material exhibits enhanced electron transport mechanisms and plasmonic effects. The resulting hybrid offers a unique multi-functional profile—combining high hardness and elastic modulus with the catalytic and antimicrobial prowess of 99.99% pure nanosilver. This research-grade composite is engineered for high-tech integration where structural integrity, thermal stability, and superior electrical conductivity must coexist.

Technical Properties

Applications

• Energy Storage: CNT–Ag hybrids are used in lithium-ion batteries and supercapacitors, where CNTs provide conductive pathways and silver enhances electron transport, cycle stability, and electrode durability. They also support hydrogen storage through hybrid porosity.
• Electronics & Optoelectronics: Applied in transistors, flat panel displays, and solar cells, CNT–Ag composites combine conductivity with plasmonic effects of silver, improving charge transport, optical performance, and thermal stability. They are also used in photoluminescence devices and electromagnetic shielding.
• Biomedical & Biosensing: Silver’s antimicrobial and bioactive properties make CNT–Ag hybrids suitable for biosensors, drug delivery, and nanoprobes. They enable sensitive detection, controlled release, and magnetic/optical guidance in biomedical applications.
• Composites & Structural Materials: As fillers in polymer, ceramic, and metal composites, CNT–Ag hybrids improve tensile strength, hardness, and elastic modulus while adding electrical conductivity. They are valuable in aerospace, automotive, and protective materials requiring multifunctionality.
• Catalysis & Environmental: CNT–Ag hybrids act as efficient catalysts in chemical and electrochemical reactions, leveraging silver’s catalytic activity and CNT’s conductive scaffolds. They are also used in gas-discharge tubes, pollutant remediation, and environmental sensing.
