Abstract
Carbon nanotube structures are disclosed in which nanotubes are disposed over a porous support such as a foam, felt, mesh, or membrane. Techniques of making these structures are also disclosed. In some of these techniques, a support is pretreated with a templated surfactant composition to assist with the formation of a nanotube layer.
Claims19
A process of making a porous, carbon nanotube-containing structure, comprising:
- providing a support material having through-porosity;
- depositing seed particles on the support material to form a seeded support material;
- and
- heating the support material and simultaneously exposing the seeded support to a carbon nanotube precursor gas to grow carbon nanotubes on the surface of the seeded support material.
A porous carbon nanotube containing structure comprising:
- a large pore support having through porosity;
- and
- carbon nanotubes disposed over the large pore support;
- and further comprising a mesoporous silica film disposed between the large pore support and the carbon nanotubes.
A heat exchanger comprising a porous carbon nanotube containing structure comprising:
- a large pore support having through porosity;
- and
- carbon nanotubes disposed over the large pore support.
A method of making a carbon nanotube containing structure, comprising:
- providing a support;
- applying a surfactant template composition over the support;
- forming a solid, silica-containing layer from the surfactant template composition that adheres to the support;
- and
- growing carbon nanotubes on the silica-containing layer.
A microchannel heat exchanger comprising:
- at least one microchannel;
- and
- carbon nanotubes disposed within at least one of said microchannels.
A filter comprising a porous carbon nanotube containing structure comprising:
- a large pore support having through porosity;
- and
- carbon nanotubes disposed over the large pore support.
A porous carbon nanotube containing structure comprising:
- a large pore support having through porosity;
- and
- carbon nanotubes disposed over the large pore support wherein the large pore support is a honeycomb or metal mesh.
A porous carbon nanotube containing structure comprising:
- a large pore support having through porosity;
- and
- carbon nanotubes disposed over the large pore support;
- further comprising mesoporous silica disposed within the large pores of the support, wherein the mesoporous silica substantially fills the large pores.
