Carbon Nanotube Suspensions We acid treat our carbon nanotubes to functionalize them with carboxyl (COOH) groups. We then suspend the carboxylated nanotubes in water or dimethylformamide (DMF). These suspensions are prepared from our PD15L<1 or L1-5 micron products or aligned carbon nanotubes, and are stable for months in our lab. Different nanotubes, concentrations and solvents are available upon request. Other functional groups such as amines are also a NanoLab specialty.

Applicable duties and taxes are paid separately upon custom clearance.
