(-COOH) Functionalized Single Walled Carbon Nanotubes

Purity: > 60%, SSA: >407m2/g, Dia: 1-2 nm

COOH-functionalized single-walled carbon nanotubes (SWCNTs–COOH) are one-atom-thick graphene sheets rolled into cylindrical nanostructures with diameters of 1–2 nm and lengths up to 30 µm. Produced via chemical vapor deposition (CVD), these black powder nanotubes exhibit >60% purity, 2.73 wt% –COOH content, and a specific surface area exceeding 407 m²/g. Their exceptional thermal, mechanical, and electrical properties—combined with enhanced dispersion and interfacial bonding from –COOH functionalization—make them highly suitable for integration into advanced polymer and composite systems.
