This product is a water-based dispersion of multi-walled carbon nanotubes (MWCNTs) whose surfaces carry covalently bonded carboxyl (-COOH) groups. It contains 5 wt% nanotubes with a purity above 95%, supplied ready to use in aqueous formulations.
The carboxyl groups make the nanotubes more hydrophilic, which keeps the suspension colloidally stable over time and limits re-agglomeration without relying on large amounts of surfactant. The tubes have an outer diameter of 5-15 nm and a length of 10-30 µm, giving a high aspect ratio, and a specific surface area of 220-300 m²/g.
Because the functional groups act as chemical anchoring points, the material suits work that depends on strong interfacial bonding and surface reactivity, such as incorporation into polymer matrices, biosensor fabrication and other water-based systems.
- Reinforcing epoxy, polyurethane and other water-soluble resins, where the -COOH groups bond chemically with the matrix to raise tensile strength and thermal stability.
- Covalent immobilisation of proteins, enzymes or DNA for electrochemical biosensors and drug delivery research.
- Water purification studies targeting adsorption of heavy metals and organic micropollutants.
- Dispersing into concrete and mortar to produce conductive, self-sensing cementitious materials with improved fracture toughness.
- Conductive additive for aqueous-processed battery and supercapacitor electrodes, supporting a uniform conductive network and better electrolyte wetting.
- Modifying electrode surfaces for electrocatalysis and analytical electrochemistry.
