Carboxyl (COOH) functionalized single walled carbon nanotube powder, 98 wt% purity, 1-2 nm outer diameter, length over 100 um. The carboxyl groups improve wetting in water-borne systems and give reactive sites for coupling to epoxy, polyurethane and other polymer matrices. Functional group content is specified on request; the technical data sheet is available below. This is a carboxyl (COOH) functionalized single walled carbon nanotube powder with 98 wt% purity, a 1-2 nm outer diameter and a length over 100 um. The carboxyl groups on the tube surface improve dispersion in water-borne systems and provide sites for covalent coupling to polymer matrices, which makes this grade a fit for epoxy and polyurethane systems and 3D-printing inks. An OH functionalized version is available as a special order; contact us for lead time. Specifications - Grade code: CTI-COOH - Functional group: Carboxyl (COOH) - Functional group content: Specification pending, contact us - Outer diameter: 1-2 nm - Purity: 98 wt% - Length: >100 um - Specific surface area (BET): >800 m2/g Values are typical of production and are not a lot-specific guarantee. Each shipment includes a Certificate of Analysis. Applications - Water-borne dispersions and coatings. - Epoxy and polyurethane systems. - Covalent coupling to polymer matrices. - 3D-printing inks. Representative data from the TDS for the SWCNT powder series: in polymers, percolation occurs at 0.05-0.2 wt% net SWCNT, with permanent antistatic behavior and no carbon sloughing. Application results depend on formulation, equipment and process conditions; confirm with your own trials. Dispersion and handling: Disperse by high-shear mixing, bead milling or probe sonication in water (with a dispersant) or resin carriers. Store sealed and dry at room temperature. Use local exhaust and respiratory protection with dry powder.

Silver nanowire (AgNW) ink is the leading solution for transparent conductive electrodes (TCEs) that require both high conductivity and optical transparency. At loadings that achieve sheet resistance below 10 Ohm/sq, AgNW films maintain optical transmittance above 85% — performance that rivals ITO at a fraction of the cost and with far superior flexibility. Unlike ITO, silver nanowire electrodes do not crack under bending, making them essential for rollable displays and conformable biosensors. Cheap Tubes synthesizes 30 nm outer diameter silver nanowires in-house at our Vermont facility, giving us direct quality control over aspect ratio, concentration, and lot-to-lot consistency — shipped at 25 mg/mL in isopropanol (IPA). Cheap Tubes supplies silver nanowire ink for transparent electrode applications in touch screens, OPV, and flexible electronics. Both ink types are formulated for compatibility with screen printing, gravure, flexographic, and inkjet deposition methods. Silver nanowire ink is the choice when optical transparency is required alongside low sheet resistance.

Amine | -NH₂ | Basic, highly water-dispersible; reacts with COOH, epoxides, aldehydes | Drug delivery, biosensors, crosslinked epoxy composites Amine (-NH2) groups are introduced via diamine coupling to -COOH and provide direct bonding to epoxy resins and conjugation chemistry to biomolecules via standard NHS/EDC coupling. -COOH and -NH2 functionalized MWCNTs are the standard substrates for biomolecule conjugation... use glutaraldehyde or NHS-PEG-NHS linkers between -NH2 surfaces and amine-bearing biomolecules. For dispersion in aqueous biological or analytical applications, -COOH and -NH₂ groups provide colloidal stability through electrostatic repulsion (high negative or positive zeta potential) without requiring surfactants that would need to be removed in downstream processing. This makes functionalized CNTs the preferred choice for drug delivery systems, biosensors, and diagnostic conjugation chemistry.
