(-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.
• Electronics: With excellent electrical conductivity (98 S/cm), these CNTs are applied in transistors, flat‑panel displays, and gas‑discharge tubes, supporting miniaturized and high‑performance electronic devices.
• Energy Storage: Functionalized double‑walled CNTs serve as conductive additives in lithium batteries and supercapacitors, enhancing charge transport, cycle stability, and energy density.
• Catalysis: The large specific surface area (370 m²/g) and hydroxyl groups provide active sites for catalytic reactions, making them suitable as catalyst supports in chemical and electrochemical processes.
• Nanotechnology Tools: Their controlled short length and functional groups enable use as nanoprobes, templates, and photoluminescent materials in advanced research and device fabrication.
• Hydrogen Storage: The layered structure and functionalization improve adsorption capacity, offering potential for hydrogen storage applications in clean energy systems.
• Solar Energy: These CNTs are explored in solar cells as conductive scaffolds and charge transport layers, contributing to higher efficiency in photovoltaic devices.
