(-OH) Functionalized Short Length Double Walled Carbon Nanotubes

Purity: > 65%, OD: 2-4 nm

(-OH) Functionalized Short Length Double Walled Carbon Nanotubes are advanced nanomaterials produced via CVD, offering controlled dimensions (OD 2–4 nm, length 0.5–2.5 µm) and high surface area (370 m²/g). Hydroxyl groups improve dispersibility and chemical reactivity, while excellent electrical conductivity (98 S/cm) enables integration into energy storage, electronics, composites, and biomedical research applications.

Technical Properties

Applications

• Medicine: The hydroxyl functionalization enhances biocompatibility, enabling use in drug delivery systems and biosensors for targeted therapies and diagnostic applications.
• Mechanics / Composites: Their short length and high aspect ratio allow effective reinforcement in polymer, ceramic, and metal matrices, improving mechanical strength, toughness, and electrical conductivity of CNT composites.
