Carbon nanotube foams with controllable mechanical properties

摘要

Syntheses of carbon nanotubes (CNT) are disclosed. The syntheses can take place on a thermally oxidized silicon surface placed inside a furnace prior to a reaction. The setup can have many variables that could affect the resulting CNT arrays, including flow rate and composition of carrier gas, flow rate and composition of precursor solution, and temperature. By varying such variables the density of the resulting CNT arrays can be controlled.

主权项

1. A method for controlling mechanical properties in a carbon nanotube foam structure, the method comprising:
synthesizing the carbon nanotube foam structure by carrying a precursor solution comprising a catalyst and a carbon source in a reaction zone by way of a carrier gas, wherein the carrier gas includes hydrogen; and controlling or varying a quantity of hydrogen to affect the mechanical properties of the carbon nanotube foam structure.
