Abstract:
We synthesized very high quality single walled carbon nanotubes using ethanol as the carbon feedstock.

Alcohol grown single walled carbon nanotubes boosts the thermal conductivity of heat transfer fluids

Tokyo, Japan | Posted on May 8th, 2012

The synthesized nanotubes have a mean diameter which is less than 2 nm. Stable nanofluid dispersions were prepared using a bile salt namely sodium deoxycholate. A very small loading of 0.2 vol% of carbon nanotube resulted in approximately 15% increase in the thermal conductivity of the base fluid. Thermal boundary conductance estimates from the effective medium theory gives a value of 400 W/m2/K indicating that properly dispersed narrow diameter nanotubes have remarkable potential to increase the thermal conductivity of the fluids. Further increase in conductivity could be achieved by coating the nanotubes with noble metals to further minimize the thermal boundary resistance.
