1 By: Steven Wehmeyer

2  Amazing properties ◦ Thermal conductivity 6600 W/m-K  2-3 times higher than diamond ◦ Elastic Modulus 1-5 TPa  3-4 times higher than diamond  Steel ~.2 TPa ◦ Electrical conductivity 10^4 S/cm  Gold 4.5x10^5 S/cm  Need to be pure to take full advantage of properties

3  High Pressure catalytic decomposition of carbon monoxide (HIPCO)  Arc discharge  Laser ablation Synthesis (HIPCO)

4  Raw material ◦ High Pressure catalytic decomposition of carbon monoxide (HIPCO) from Unidym ◦ Elicarb from Swan Chemical Inc.  Oxidize  Heat  Acid reflux  Hydrochloric Acid (HCl)  Purified SWNT  Characterize ◦ Transmission Electron Microscope ◦ Thermogravimetric Analysis ◦ Raman Spectroscopy

5  Combine oxidation and acid reflux 2 ◦ H 2 O 2 for oxidizing and HCl for acid reflux  Different concentrations ◦ Acids  HCl  Nitric Acid  Sidewall damage  Acetone  Combine with carbon nanotubes and heat mixture (40-70°C) for eight hours to accelerate processes  Filter  Characterize ◦ TEM, TGA, Raman Spectroscopy
