Ossila M2395F1 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 2 nm, a length of 1 – 2 μm, a COOH content of ca. 4.03 wt%, a specific surface area of 650 m2/g and a purity above 95%. It is supplied as a black fibrous powder.
The carboxylic acid groups make the nanotubes easier to disperse in solvents and polymer resins, because they can form hydrogen bonds and chemical crosslinks. The mechanical, electrical, optical and thermal properties of pristine SWCNTs are retained. Recommended dispersants are DI water, DMF, THF, ethanol and acetone.
Published work shows SWCNT-COOH dispersing gold nanoparticles with a CuMOF (HKUST-1) in an electrochemical sensor for imatinib in human blood serum, with a linear response over 0.05 – 20.0 μM. As a conductive additive in boron-silicon alloy anodes for lithium batteries, the material stabilized B-Si colloids in NMP and gave more than 80% capacity retention after 1000 cycles.
- Electrochemical sensors, for example CuMOF-COOH-SWCNT@AuNPs electrodes for detecting imatinib in serum.
- Conductive additive for boron-silicon alloy anodes in lithium batteries.
- Reinforcement of polymers and resins to improve mechanical properties.
- Improving the electrical properties of composites and thin-film electronics.
