: A middle ground, often used for specialized optics or sensitive conductive layers. 2. Choose Your Purity & Grade
: The "workhorse." Multiple nested tubes. Ideal for strengthening polymers, battery electrodes, or anti-corrosion coatings. buy carbon nanotubes
The market is dominated by large-scale producers that have moved past lab-scale synthesis: A History of Carbon Nanotubes - AZoNano : A middle ground, often used for specialized
Purity is the primary price driver. High-purity grades (98%+) are extremely expensive and reserved for applications where every defect could disrupt electronic pathways. : A middle ground
: The "Ferrari" of the group. A single sheet of graphene. Best for high-end electronics and sensors.
: Arc-discharge SWCNTs can cost between $75 and $300 per gram depending on purity and length.
