This material requires controlled storage to prevent moisture absorption and oxidative degradation of the carboxylic functional groups. Dispersion and processing must account for potential agglomeration due to high aspect ratio and surface functionality.
- Storage Atmosphere: Store in a sealed container under inert gas (argon or nitrogen) to minimize moisture uptake and oxidation of the carboxylated surface.
- Dispersion Compatibility: The carboxylic groups enhance dispersibility in polar solvents, but sonication parameters must be optimized to avoid structural damage or excessive shortening.
- Handling Precautions: Use in a fume hood or glovebox to prevent inhalation of fine particulates, which may cause respiratory irritation.
This procedure outlines the safe handling and dispersion of carboxylated multi-walled carbon nanotubes in a polar solvent for composite or electrode fabrication. Proper sonication and solvent selection are critical to achieve a stable, homogeneous suspension.
Required Equipment: Analytical balance, Ultrasonic bath or probe sonicator, Glovebox or fume hood
- Weigh the nanotube powder
Weigh the required amount of Short-Carboxylic Multi-walled Carbon Nanotubes inside a glovebox or fume hood to avoid airborne particle exposure. - Transfer to solvent
Transfer the powder into a clean glass vial containing the chosen polar solvent (e.g., deionized water, ethanol, or DMF) at a concentration of 0.5–2 mg/mL. - Sonicate the mixture
Sonicate the mixture in an ultrasonic bath for 30–60 minutes or using a probe sonicator at low power (20–30% amplitude) for 10–15 minutes to achieve uniform dispersion. - Inspect for agglomerates
Inspect the dispersion visually for large agglomerates; if present, increase sonication time in short intervals or adjust solvent polarity. - Use immediately or store
Use the dispersion immediately for further processing, or store in a sealed container at 2–8°C for up to 48 hours to minimize re-agglomeration.
What is the purity specification of these short carboxylic MWCNTs and how does it affect research reproducibility?
The product is specified with a purity of >95% as listed in the Technical Specifications table. This purity level is standard for research-grade carbon nanotubes and supports consistent experimental results. The selection notes recommend matching the purity specification to the intended dispersion, composite, or electrode workflow.
Which research workflows are these short carboxylic MWCNTs suitable for?
According to the selection and use notes, this material can be matched to dispersion, composite, film, electrode, conductivity, or nanocarbon research workflows. The carboxylated functional group and specific dimensions (OD 8-15 nm, length 0.5-2 μm) are provided for model matching against the required experiment.
What information must be confirmed before ordering bulk quantities of these MWCNTs?
The product description explicitly states that bulk quantity requirements should be confirmed when requesting quotation support. The quotation details also specify that nanotube wall type, outer diameter, length, purity, functional group, and package size should be reviewed before quotation to ensure correct specification and availability.
Short-carboxylic multi-walled carbon nanotubes (OD 8-15 nm, length 0.5-2 µm, purity >95%) provide a functionalized nanocarbon platform for dispersion, composite, electrode, and conductivity workflows, with the carboxyl group enhancing compatibility with polar matrices and aqueous processing.
Positive
- Carboxyl functionalization for dispersion: The short-carboxylic modification introduces polar surface groups that improve dispersibility in aqueous and polar solvent systems, facilitating integration into composite, film, and electrode formulations without aggressive surfactants.
- High purity >95% for consistent results: Purity exceeding 95% minimizes amorphous carbon and metal catalyst residues, reducing batch-to-batch variability in conductivity, mechanical reinforcement, and electrochemical performance.
Trade-offs
- Short length limits percolation networks: The 0.5-2 µm length range reduces the aspect ratio compared to longer MWCNTs, potentially requiring higher loading fractions to achieve equivalent electrical percolation or mechanical reinforcement in composite systems.
- Bulk quantity confirmation required: Procurement notes indicate that bulk quantity requirements must be confirmed before quotation, suggesting potential lead time or minimum order constraints for larger-scale laboratory or pilot projects.
