How does the graphitization process affect the electrical conductivity and thermal stability of these SWCNTs compared to non-graphitized single-walled carbon nanotubes?

The graphitized structure of these SWCNTs delivers enhanced electrical conductivity and thermal stability compared to non-graphitized counterparts. This improvement is explicitly stated in the product's Key Features & Advantages, supported by the >99.9 wt% purity level, which minimizes defect-induced scattering and thermal resistance. While graphitization reduces surface functional groups for chemical modification, the trade-off yields superior electronic and thermal transport for demanding nanoelectronics and energy storage applications.

Can these graphitized SWCNTs be directly dispersed in aqueous solvents for conductive ink formulations without additional surfactants?

Direct aqueous dispersion of these graphitized SWCNTs is not feasible without surfactants or polymeric stabilizers due to their hydrophobic, highly graphitized surface. The material is supplied as a black powder with >99.9 wt% purity and is designed for applications such as conductive inks and coatings, which require tailored dispersion protocols. Researchers must account for the reduced surface functionality caused by graphitization when formulating aqueous suspensions.

What storage conditions are necessary to maintain the >99.9 wt% purity of graphitized SWCNTs over extended research timelines?

The black powder form of these graphitized SWCNTs requires storage in a sealed, dry container at room temperature to preserve the stated >99.9 wt% purity. Exposure to ambient moisture or airborne particulates can contaminate the high-surface-area nanotubes, compromising performance in sensitive applications like sensors and composite materials. The product description emphasizes high purity as a critical feature, making controlled storage essential for reliable experimental outcomes.
