(-OH) Functionalized Double Walled Carbon Nanotubes

Purity: > 65%, Length: 48 µm

(-OH) Functionalized Double Walled Carbon Nanotubes (DWCNTs, Purity >65%, Length 48 µm) are advanced nanomaterials designed for enhanced chemical reactivity and dispersion. The hydroxyl (-OH) groups on the outer wall enable strong interfacial bonding with polymers, ceramics, and biomolecules, while the inner wall preserves the intrinsic electrical and mechanical properties of the nanotubes. This dual functionality provides superior processability, improved compatibility with aqueous and organic systems, and stable integration into composites and coatings. Offered in reliable purity and consistent morphology, these functionalized DWCNTs deliver both performance and versatility for research and industrial innovation.

Technical Properties

Applications

• Energy and Storage Systems: Hydroxyl-functionalized DWCNTs improve dispersion in electrode matrices, enhancing conductivity and cycle stability in lithium-ion and lithium-sulfur batteries. Their surface chemistry also facilitates better integration into supercapacitors and hydrogen storage systems, supporting efficient energy conversion and storage.
• Electronics and Optoelectronics: The presence of –OH groups enables uniform film formation and stronger interfacial bonding in electronic devices. Functionalized DWCNTs are applied in transparent conductive coatings, field-effect transistors, and solar cells, where improved charge transport and stability are critical.
• Composites and Mechanical Applications: (-OH) functionalization enhances compatibility with polymer and ceramic matrices, reducing agglomeration and enabling homogeneous dispersion. This results in composites with improved mechanical strength, toughness, and durability, suitable for aerospace and automotive applications.
• Chemical and Catalysis Applications: Hydroxyl groups provide anchoring sites for catalytic nanoparticles, making functionalized DWCNTs effective supports in heterogeneous catalysis and gas sensors. Their modified surface chemistry improves selectivity and stability in chemical reactions and electrochemical systems.
• Biomedical and Environmental Applications: Functionalized DWCNTs exhibit better solubility in aqueous environments, enabling safer and more effective use in drug delivery and biosensing. Their reduced cytotoxicity compared to pristine CNTs makes them attractive for biomedical platforms. Additionally, they adsorb heavy metals and organic pollutants, offering solutions for environmental remediation.
