(-COOH) Functionalized Multi Walled Carbon Nanotubes Water Dispersion

5 wt%, Purity: >95%, OD: 5-15 nm, Length: 10-30 µm

(-COOH) Functionalized Multi-Walled Carbon Nanotube Water Dispersion is a high-purity aqueous suspension featuring chemically modified nanotubes for enhanced performance. The covalent attachment of carboxyl groups (-COOH) to the nanotube surfaces significantly improves their hydrophilic nature, ensuring long-term colloidal stability and preventing re-agglomeration without the heavy use of surfactants. With a high aspect ratio (5-15 nm diameter and 10-30 µm length) and a massive specific surface area of 220-300 m²/g, this dispersion is engineered for applications requiring strong interfacial bonding and high chemical reactivity. The functionalized surface acting as chemical anchors makes this product superior for integration into polymer matrices, biosensors, and advanced aqueous formulations.

Applications

• Polymer Nanocomposites: The -COOH groups provide active sites for chemical bonding with epoxy, polyurethane, and other water-soluble resins, leading to drastic improvements in tensile strength and thermal stability.
• Biosensors and Medical Research: Ideal for the covalent attachment of proteins, enzymes, or DNA, making it a cornerstone material for high-sensitivity electrochemical biosensors and targeted drug delivery studies.
• Advanced Water Purification: Enhanced adsorption capacity for heavy metals and organic micropollutants due to the increased polarity and ion-exchange capabilities of the functionalized surface.
• Smart Cementitious Materials: Superior dispersion within concrete and mortar matrices to create conductive, self-sensing "smart" infrastructures with improved fracture toughness.
• Energy Storage Electrodes: Used as a high-performance conductive additive in aqueous-processed battery and supercapacitor electrodes to ensure a more uniform conductive network and better electrolyte wetting.
• Electrochemical Applications: Excellent for modifying electrode surfaces in electrocatalysis and analytical chemistry, benefiting from the rapid electron transfer facilitated by the -COOH groups.
