Diameter distribution measured by Unidym from TEM micrographs. Mean diameter ~1.0 nm.
Measured by Unidym using AFM.
Calculated. Lower limit assumes a SWNT with a diameter of 0.8nm and a length of 100nm. (0.8nm/0.245nm)(3.1414)(2carbon atoms) = 20 carbons around the circumference. For every 0.283nm length there are 4x20=80 carbon atoms.
(100nm/0.283nm)(80)(12.01) = 339,505 Amu. Assuming 2 significant digits = 3.4x105. Upper limit assumes a SWNT with adiameter of 1.2nm and a length of 1,000nm. (1.2nm/0.245nm)(3.1414)(2 carbon atoms) = 31 carbons around thecircumference. For every 0.283nm length there are 4x31 = 124 carbon atoms. (1000nm/0.283nm)(124)(12.01) = 5,262,332
Amu. Assuming 2 significant digits = 5.2x106.

Particle Size Analysis!"#$%&!
Calculated assuming single-wall nanotubes of diameter 1.0 nm arranged in crystalline “ropes” or “bundles” (inter-wallspacing 0.3 nm).
v
Value provided is for standard purified SWNTs. Raw and some super pure grades lots will have lower bulk densities. Otherproduct forms may have higher bulk densities.
vi 800oC in air. The reported figures assume that the residue is present in the product as elemental Fe, and that it is fully
converted to Fe2O3 during the TGA analysis. Hence, the TGA residual as measured is multiplied by MW Fe2/MW Fe2O3(1/1.43) to express the result as Fe.
vii Calculated using geometric arguments assuming an isolated tube. SSA for tubes in “ropes” will be lessthan the stated value. A. Peigney et al., Carbon 39 (2001), 507-514.
viii In-house, Unidym buckypaper conductivity test (4 point probe).
ix The following particle size histogram is indicative of the typical tertiary particle size distribution found in bulk powder. It
does not represent secondary particles (aggregates of individual tubes also known as ropes or bundles) nor does it
represent primary particle sizes (individual carbon nanotubes).
