(-NH2) Functionalized Single Walled Carbon Nanotubes

Purity: > 95%, SSA: > 620 m2/g

Single-walled carbon nanotubes (SWCNTs, SWNTs) comprise of one-atom-thick sheets of graphene that rolled up to form long hollow tubes. SWCNTs possess exceptional thermal, mechanical and electrical properties. These remarkable properties lead to advances in performance in a wide range of materials and devices. Amino (-NH2) functionalization significantly improves the nanotubes' chemical reactivity and dispersion stability in various solvents and polymer matrices. These nanotubes provide active sites for covalent bonding, making them ideal for high-performance applications where interfacial adhesion and structural integrity are critical. 

Technical Properties

Applications

• Biomedical & Nano-Biotechnology: The presence of amino (-NH2) groups significantly enhances the reactivity of nanotubes with biological molecules like proteins and DNA. This functionalization provides a versatile platform for targeted drug delivery systems, high-sensitivity biosensors, and advanced gene therapy applications.
• Advanced Composite Systems: Amino-functionalization provides excellent covalent bonding sites that improve interfacial adhesion between the nanotubes and polymer matrices, particularly in epoxies and polyamides. This results in superior mechanical reinforcement, improved thermal stability, and enhanced electrical conductivity in structural composites.
• Energy Storage & Conversion: NH2 functionalized SWCNTs are highly effective in stabilizing charge transfer processes. They are actively utilized in enhancing the performance and cycle life of lithium-ion battery anodes, supercapacitors, and next-generation fuel cells by providing a conductive network with high surface area. 
• Chemical Sensing & Environmental Remediation: The amino groups act as selective reactive sites for the detection of specific gases and pollutants. Their high specific surface area (>620 m²/g) and surface reactivity make them ideal for capturing heavy metal ions and developing advanced filtration membranes.
