(-COOH) Functionalized Single Walled Carbon Nanotubes

Purity: > 92%, SSA: 370 m2/g, Dia: 1.0 nm

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. Single-walled carbon nanotubes
are actively used in diverse area including energy storage, molecular electronics, nanomechanial devices, composites
and bio-sensing. You can buy (-COOH) Functionalized Single Walled Carbon Nano Tubes with low prices and high purity.

Applications:

• Biomedical & Life Sciences: Carboxyl-functionalized SWCNTs offer excellent aqueous dispersibility and biocompatibility, making them ideal for targeted drug delivery, biosensors, and bioimaging. The -COOH groups enable covalent bonding with biomolecules, while the high surface area and narrow diameter support efficient cellular interaction and molecular transport.
• Chemical & Catalytic Applications: The presence of carboxyl groups enhances chemical reactivity and metal ion coordination, making these nanotubes highly effective in heterogeneous catalysis, photocatalysis, and template-assisted synthesis. Their high SSA and edge-rich morphology promote active site exposure and facilitate surface functionalization.
• Composite Engineering & Coatings: These SWCNTs disperse uniformly in polar solvents and polymer matrices, improving mechanical reinforcement, thermal stability, and electrical conductivity in advanced composites. Their shortened length and functional surface chemistry support strong interfacial bonding and processability in coatings and adhesives.
• Energy Storage & Conversion: With high purity and tailored surface chemistry, -COOH SWCNTs enhance performance in lithium-ion batteries, supercapacitors, and fuel cells. Their high surface area and conductivity enable efficient charge transfer, stable electrode–electrolyte interfaces, and improved cycle life.
• Electronics & Optoelectronics: These nanotubes are used in gas-discharge tubes, transparent conductive films, flat panel displays, and thin-film transistors, where their nanoscale dimensions and surface functionality support efficient charge transport, photoluminescence, and device integration.
