HiPco SWCNT represent a benchmark for small diameter nanotubes both in the academic community and for industrial and commercial applications. We offer three grades of purity for this unique material. Raw HiPco SWCNT contain up to 15% of iron, whereas Purified HiPco SWCNT and Superpurified HiPco SWCNT contain less than 10 and 5% iron respectively. Properties Individual SWNT Diameter i~0.8 – 1.2 nm Individual SWNT Length ii~100 – 1000 nm Calculated Molecular Weight iii~3.4×10 5 – 5.2×10 6 Amu Color Black Morphology Dry powder of nanotubes bundled in ropes Maximum Density iv 1.6 g/cm 3 Bulk Density v~0.1 g/cm 3 TGA Residue as Fe vi – Raw – Pure – Super Pure TGA 1 st Derivative Peak Temperature Raw ~350 – 410°C Pure ~470 – 490°C Super Pure ~510 – 540°C TGA Onset Temperature Raw ~350°C Pure ~440°C Super Pure ~450°C Maximum Surface Area vii 1315 m 2/g BET Surface Area~400 – 1000 m 2/g Buckypaper Resistance viii~0.2 – 2Ω Moisture Content SEM TEM Raman TGA Profile Particle Size Analysis i Diameter distribution measured by Unidym from TEM micrographs. Mean diameter ~1.0 nm. ii Measured by Unidym using AFM. iii Calculated. Lower limit assumes a SWNT with a diameter of 0.8nm and a length of 100nm. (0.8nm/0.245nm)(3.1414)(2 carbon atoms) = 20 carbons around the circumference. For every 0.283nm length there are 4×20=80 carbon atoms. (100nm/0.283nm)(80)(12.01) = 339,505 Amu. Assuming 2 significant digits = 3.4×10 5. Upper limit assumes a SWNT with a diameter of 1.2nm and a length of 1,000nm. (1.2nm/0.245nm)(3.1414)(2 carbon atoms) = 31 carbons around the circumference. For every 0.283nm length there are 4×31 = 124 carbon atoms. (1000nm/0.283nm)(124)(12.01) = 5,262,332 Amu. Assuming 2 significant digits = 5.2×10 6. iv Calculated assuming single-wall nanotubes of diameter 1.0 nm arranged in crystalline "ropes" or "bundles" (inter-wall spacing 0.3 nm). v Value provided is for standard purified SWNTs. Raw and some super pure grades lots will have lower bulk densities. Other product forms may have higher bulk densities. vi 800°C in air. The reported figures assume that the residue is present in the product as elemental Fe, and that it is fully converted to Fe 2 O 3 during the TGA analysis. Hence, the TGA residual as measured is multiplied by MW Fe 2/MW Fe 2 O 3 (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 less than 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).

Our PureWave Graphene Nanoplatelets (GNP) material is composed of thin, highly dispersible 4-7 layer graphene nanoplatelets with very low oxygen and polyaromatic hydrocarbon (PAH) content. The turbostratic and wavy morphology of the material leads to an unequaled ability to be dispersed in a variety of solvents and resins. Furthermore, the unique plasma process used to grow our PureWave Graphene Nanoplatelets is easy to scale and thus produces a low cost, but high-quality product. Our unique and patent-protected growth process, based on inductively-coupled plasma, allows us to produce this material at over 100 g/hour, enabling commercial graphene applications such as energy storage and conductive inks as well as elastomers and resins. Using our special milling process, our PureWave Graphene nanoplatelet powder can be effectively dispersed into a water-soluble polymer matrix. This allows for the creation of a material with very advantageous properties at high loadings (up to 8 wt% Graphene) that can be utilized for numerous applications to provide thermal stability, mechanical property enhancement, dielectric constant improvement, and electrical conductivity.
