Title of Invention | CARBON NANOTUBES AND THEIR SYNTHESIS |
---|---|
Abstract | A process for the synthesis of single walled and multiwalled nanotubes comprising the steps of heating a furnace to 500°C in argon flow; allowing hydrogen gas into the furnace for almost 30 min; stopping the hydrogen flow and raising the temperature of the furnace to the deposition temperature in the range825 -860 (for production of alloy eneapsulated MWNTS) or 930-970°C (for production of SWNTS); allowing methane into the furnace for about 30 min; stopping the methane flow and the furmace cooled to room temperature, the argon flow being maintained throughout the process with the generation of hydrogen as a byproduct; removing the quartz reactor and quartz boat with nanotube deposit from the furnace |
