(-OH) Functionalized Single Walled Carbon Nanotubes
Purity: > 65%, SSA: 400 m2/g, Dia: 1.0 nm
Single walled carbon nanotubes (SWCNTs, SWNTs) consist of one-atom-thick graphene sheets rolled into long, hollow cylindrical structures. These SWCNTs exhibit outstanding thermal, mechanical, and electrical properties, contributing to enhanced performance across a wide range of materials and devices. They are used extensively in areas such as energy storage, molecular electronics, nanomechanical devices, composites, and bio-sensing. Our (-OH) Functionalized Single Walled Carbon Nanotubes offer competitive performance and value compared to similar products.

Applications:
Biomedical & Biosensing: Hydroxyl-functionalized SWCNTs offer improved aqueous dispersibility and biocompatibility, making them suitable for biosensors, drug delivery systems, and bioimaging platforms. Their surface chemistry supports further conjugation with biomolecules.
Catalysis & Surface Chemistry: The -OH groups enable strong interaction with metal ions and catalytic species, enhancing performance in heterogeneous catalysis, photocatalysis, and template-assisted synthesis.
Polymer & Composite Integration: Functionalized SWCNTs disperse more uniformly in polar solvents and polymer matrices, improving mechanical reinforcement, thermal stability, and electrical conductivity in advanced composites.
Energy Devices: Their tailored surface chemistry supports better electrode–electrolyte interaction in supercapacitors, lithium-ion batteries, and fuel cells, contributing to higher charge transfer efficiency and cycle stability.
