Ossila M2395C1 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 of 1 – 2 nm, a length of 1 – 3 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.
Functionalization keeps the mechanical, electrical, optical and thermal performance of pristine SWCNTs. The surface carboxylic acid groups make the tubes easier to disperse in solutions and polymer resins, because they can form hydrogen bonds and chemical crosslinks. Recommended dispersants are DI water, DMF, THF, ethanol and acetone.
Published work has used SWCNT-COOH to disperse gold nanoparticles with a CuMOF (HKUST-1) in an electrochemical imatinib sensor for human blood serum, which gave a linear response over 0.05 – 20.0 μM. The nanotubes have also served as a conductive additive in boron-silicon alloy anodes for lithium batteries. There they kept B-Si colloids in NMP stable, and the anode retained more than 80% of its capacity 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 composites and thin-film electronics, including transparent electrodes.
