Carboxyl (COOH) functionalized, surfactant free carbon nanotube suspensions. To create carboxyl (COOH) functional groups on the sidewall of the carbon nanotubes, we treat them in a mixture of hot nitric & sulfuric acids. After washing the nanotubes to remove excess acid, they may be dispersed. We offer suspended, carboxylated nanotubes in water, ethanol, acetone or dimethylformamide (DMF). These nanotube paint - like suspensions are prepared from our standard single and multiwall carbon nanotubes, and are stable for months in our lab. These can be inkjet printed thru Fuji Dimatix printers, or other printers. Suspensions and paints having different concentrations, special solvents, or large volumes are available; send a request by email. Please note Suspensions are made to order and can sometimes take a week. If you need your suspension sooner, please email us directly at sales@nano-lab.com. Send us custom suspension requests to info@nano-lab.com. Shipping charges are prepaid and added to an invoice. Applicable duties and taxes are paid separately upon custom clearance.
