Ossila M2014L2 is a grade of carboxylated single-walled carbon nanotubes (SWCNT-COOH): oxidized SWCNTs carrying carboxylic acid groups on their surface. This grade has a diameter below 2 nm, lengths of 5 – 25 μm, a COOH content of 2.7 wt%, a specific surface area of 370 m2/g and a purity above 92%. It is supplied as a black fibrous powder in 250 mg and 500 mg packs.
The functionalized tubes keep the mechanical, electrical, optical and thermal properties of pristine SWCNTs. The carboxylic acid groups can form hydrogen bonds and chemical crosslinks, which helps the nanotubes disperse in solutions and polymer resins. Recommended dispersants are DI water, DMF, THF, ethanol and acetone.
Reported uses include electrochemical sensing and lithium battery anodes. In one sensor, SWCNT-COOH dispersed gold nanoparticles together with a CuMOF (HKUST-1) to detect imatinib in human blood serum, with a linear response over 0.05 – 20.0 μM. As a conductive additive for boron-silicon alloy anodes, the material stabilized B-Si colloids in NMP and gave more than 80% capacity retention after 1000 cycles.
- Electrochemical sensors, such as CuMOF-COOH-SWCNT@AuNPs electrodes for monitoring imatinib in human serum.
- Conductive additive for boron-silicon alloy anodes in lithium batteries.
- Reinforcement of polymers and nanocomposites such as PDMS to improve mechanical properties.
- Improving the electrical properties of materials and thin-film electronics.
