Description
Single Walled Carbon Nanotubes (SWCNTs, SWNTs), Purity > 95%, Diameter: 1.0 nm
Product Description: Single Walled Carbon Nanotubes (SWCNTs) consist of a single graphene sheet rolled into a seamless cylindrical structure with remarkable nanometer-scale precision. Known for their extraordinary electrical, thermal, and mechanical characteristics, SWCNTs are among the most advanced nanomaterials available today. Their high aspect ratio, unique one-dimensional structure, and quantum confinement effects make them indispensable in numerous high-performance applications across electronics, energy, and materials science.
These nanotubes are produced through the decomposition of methane over a cobalt-based catalyst and subsequently purified via deep air oxidation. This process yields a material with very low amorphous carbon content and excellent crystalline quality, making them particularly suitable for applications requiring high electrical conductivity and transparency.
Applications: SWCNTs are used extensively in:
- Transparent conductive films (TCFs) for touchscreens, OLEDs, and flat panel displays
- Thin-film solar cells
- Molecular electronics and nanomechanical systems
- Energy storage devices like supercapacitors and lithium-ion batteries
- High-strength and lightweight nanocomposites
- Bio-sensing and biomedical devices
Transparent conductive films made from these SWCNTs can achieve over 80% transparency and sheet resistances below 200 Ω/sq, outperforming many traditional materials.
