Ultra-High Purity Hydroxylated Single-Walled Carbon Nanotubes (SWCNTs)

Product Overview
Ultra-high purity hydroxylated single-walled carbon nanotubes (SWCNTs) are seamless hollow tubes made from a single layer of graphite hexagonal lattice. They feature an extremely high surface area and exceptional electrical, thermal, and mechanical properties. The diameter of these nanotubes ranges from 1 to 2 nanometers, with lengths extending to micrometers or even longer. Hydroxylation treatment improves their water solubility and dispersion, making them highly versatile across various applications. Manufactured using the floating catalyst method, these nanotubes offer high purity and excellent stability, ideal for use in electronics, energy, composite materials, and more.

Key Features

• Excellent Electrical Conductivity: High electrical conductivity and low resistance, allowing for efficient current transmission. Their electrical performance is comparable to that of excellent conductors like silver and copper.
• High Thermal Conductivity: Exceptional thermal conductivity, making these nanotubes valuable for high-efficiency heat dissipation and thermal management systems.
• Unique Mechanical Properties: Extremely high tensile strength (100-200 GPa) and Young's modulus (up to 1 TPa), ideal for reinforcing composite materials.
• High Chemical Stability: Maintains stability in most chemical environments, resistant to acids, bases, and oxidizing agents.
• Optical Properties: Absorbs and scatters light at specific wavelengths, and can emit light under certain conditions, suitable for optoelectronic devices.
• High Flexibility: Can bend and fold without breaking, making it perfect for flexible electronic devices.

Applications

• Electronics: Used to manufacture high-efficiency, miniaturized integrated circuits, field-effect transistors, and flexible electronic devices.
• Energy: In lithium-ion batteries, SWCNTs are used as electrode materials to enhance charge/discharge performance and extend cycle life. They are also suitable for manufacturing supercapacitors, increasing energy and power density.
• Composite Materials: When added to polymers and other matrix materials, SWCNTs significantly improve strength, stiffness, and toughness.
• Sensors: With high sensitivity and selectivity, SWCNTs are ideal for detecting gases, chemicals, biological molecules, and cells.
• Nanomechanics: Used to build micro-mechanical components, such as nano motors.
• Aerospace: Used in manufacturing lightweight, high-strength components for aircraft and spacecraft.
• Other Applications: SWCNTs are also widely used in catalysts, field emitters, conductive films, and bio-nanomaterials.
