Nanointegris ultrapure SWCNTs solution

Single-Walled Carbon Nanotubes (SWCNTs), often referred to as the "quasi-one-dimensional nanomaterial with superior comprehensive performance", are cylindrical nanostructures formed by rolling a single layer of graphene into a tube at a specific angle. The Nanointegris ultrapure SWCNTs solution is a high-purity dispersion product of SWCNTs, developed to address the challenges of efficient dispersion and stable application of SWCNTs in industrial and research scenarios.
Fundamental Structural Characteristics: SWCNTs have an extremely small diameter range of 0.6-2 nm, with the minimum diameter reaching approximately 0.4 nm. This ultra-fine size enables them to freely enter cells (a key advantage for biomedical applications) and form unique microstructures when assembled into macroscopic materials. The structural diversity of SWCNTs—determined by their chiral indices (n, m)—leads to significant differences in properties; for example, some exhibit semiconductor properties, while others show metallic conductivity, laying the foundation for their multi-field application.
Market and Industry Context: Globally, the annual production capacity of SWCNTs is currently less than 100 tons, making high-purity SWCNT solutions (like the Nanointegris ultrapure variant) a high-value product in the nanomaterial market. Traditional SWCNT products often face issues such as low purity, uneven dispersion, and poor stability, which limit their performance in high-end fields (e.g., semiconductor devices, high-efficiency energy storage). The Nanointegris ultrapure SWCNTs solution is developed to fill this gap, providing a reliable material basis for cutting-edge research and industrial upgrading.

Superior Purity for High-End Applications: Compared with ordinary SWCNT solutions, its ultra-high purity ensures no interference from impurities in sensitive scenarios. For example, in semiconductor device manufacturing, it avoids performance degradation of devices caused by metal ion contamination, and in biomedical applications, it reduces potential cytotoxicity from impurities.
Enhanced Processability: The excellent dispersion stability eliminates the need for additional dispersion treatments (such as repeated ultrasonic processing) during use, reducing production costs and process complexity for customers. This advantage is particularly critical for large-scale fabrication of SWCNT-based thin films or composites.
Reliable Performance Consistency: Each batch of the solution undergoes strict quality control, ensuring consistent physical and chemical properties (e.g., conductivity, thermal conductivity, and optical absorption) across batches. This consistency is essential for industrial production, where stable product performance directly affects yield and product quality.
Broad Compatibility with Application Technologies: Its adjustable concentration and solvent compatibility enable seamless integration with existing technologies in multiple fields. For instance, in lithium-ion battery manufacturing, it can be easily mixed with electrode materials to improve conductivity; in bioimaging, it can be combined with common biological buffers for cell labeling.
