This nanomaterial requires storage in a dry environment to maintain its specified moisture content below 0.1%. Ambient humidity exposure can lead to moisture uptake and compromise electrical performance.
- Moisture Sensitivity: Store in a sealed container under dry conditions to preserve the low moisture content and prevent performance degradation.
How does the 60 nm diameter of CH carbon nanotubes affect their electrical conductivity in composite systems compared to smaller-diameter CNTs?
The CH series with 60 nm diameter achieves a resistivity of <15 mΩ·cm at 20MPa, demonstrating 2x better conductivity than the AH series in composite systems. The larger diameter likely reduces contact resistance between nanotubes, enabling efficient percolation at lower loading fractions.
What constraints exist for using CH carbon nanotubes in semiconductor or ultra-high-purity applications given their metal impurity profile?
CH carbon nanotubes contain total metal impurities <50ppm with Fe<30ppm and magnetic particles <2ppm, making them suitable for application environments requiring extremely low magnetic contamination. The >99.95% purity ensures minimal catalytic interference in sensitive chemical systems.
What storage infrastructure is recommended for CH carbon nanotubes to maintain their specified performance?
With moisture content specified at <0.1%, CH carbon nanotubes should be stored in sealed containers under dry conditions to prevent moisture uptake that could agglomerate particles and degrade dispersion quality. The material is sold exclusively for laboratory research and professional handling environments.
The ATOMFAIR® CH carbon nanotubes provide twice the conductivity of AH-series in composite systems with ultra-high purity (>99.95%) and very low metal contamination (<50 ppm). However, the moderate surface area (30-40 m²/g) limits functionalization capacity, and the stringent moisture content specification (<0.1%) necessitates anhydrous storage and handling protocols.
Positive
- Superior composite conductivity: Delivers 2x the electrical conductivity of AH-series nanotubes in composite systems, enabling enhanced performance in conductive polymers and coatings.
- Ultra-high purity with trace metals: Purity exceeds 99.95% with total metal impurities below 50 ppm (Fe <30 ppm) and magnetic particles below 2 ppm, minimizing contamination in sensitive electronic and catalytic applications.
Trade-offs
- Moderate surface area: With a surface area of only 30-40 m²/g, the available interface for functionalization, catalyst loading, or adsorption is limited compared to higher-surface-area carbon nanostructures.
- Moisture-sensitive storage required: The material's specified moisture content of <0.1% demands anhydrous storage conditions to prevent aggregation and preserve electrical properties, adding logistical overhead.
