Free-standing and aligned carbon nanotubes and synthesis thereof

One or more highly-oriented, multi-walled carbon nanotubes are grown on an outer surface of a substrate initially disposed with a catalyst film or catalyst nano-dot by plasma enhanced hot filament chemical vapor deposition of a carbon source gas and a catalyst gas at temperatures between 300° C. and 3000° C. The carbon nanotubes range from 4 to 500 nm in diameter and 0.1 to 50 μm in length depending on growth conditions. Carbon nanotube density can exceed 104 nanotubes / mm2. Acetylene is used as the carbon source gas, and ammonia is used as the catalyst gas. Plasma intensity, carbon source gas to catalyst gas ratio and their flow rates, catalyst film thickness, and temperature of chemical vapor deposition affect the lengths, diameters, density, and uniformity of the carbon nanotubes. The carbon nanotubes of the present invention are useful in electrochemical applications as well as in electron emission, structural composite, material storage, and microelectrode applications.

Curing binder material for carbon nanotube electron emission cathodes

A binder material, inorganic polymer, is used to formulate carbon nanotube pastes. This material can be cured at 200° C. and has a thermal-stability up to 500° C. Low-out gassing of this binder material makes it a good candidate for long life field emission devices. Due to better adhesion with this binder material, a strong adhesive peelable polymer from liquid form can be applied on the CNT cathode to achieve a uniform activation with even contact and pressure on the surface. The peelable polymer films may be used both as an activation layer and a mask layer to fabricate high-resolution patterned carbon nanotube cathodes for field emission devices using lithographic processes.

FED cathode structure using electrophoretic deposition and method of fabrication

A method of fabricating a field emission device cathode using electrophoretic deposition of carbon nanotubes in which a separate step of depositing a binder material onto a substrate, is performed prior to carbon nanotube particle deposition. First, a binder layer is deposited on a substrate from a solution containing a binder material. The substrate having the binder material deposited thereon is then transferred into a carbon nanotube suspension bath allowing for coating of the carbon nanotube particles onto the substrate. Thermal processing of the coating transforms the binder layer properties which provides for the adhesion of the carbon nanotube particles to the binder material.

Processing apparatus which performs predetermined processing while supplying a processing liquid to a substrate

Above a substrate holder 1, an ordinary fluid jet nozzle 2 which is capable of injecting drops of a solution having ordinary particle diameters, a fine fluid jet nozzle 3 which is capable of injecting drops of a solution having fine particle diameters which are smaller than the ordinary particle diameters, and a regular reflection laser displacement gauge 4 are disposed. These are attached on the same plate, thereby forming a head 10. The head 10 freely moves in directions X, Y and Z, as an X-axis drive portion 41, Y-axis drive portions 42 and 43 and a Z-axis drive portion 44 operate in accordance with operation commands received from a controller 50 which controls the apparatus as a whole. It is therefore possible to set the head 10 to a predetermined position on a substrate S which is held by the substrate holder 1. Thus, the respective nozzles supply the solutions to any desired positions the substrate S.

Macroscopic ordered assembly of carbon nanotubes

The present invention is directed to the creation of macroscopic materials and objects comprising aligned nanotube segments. The invention entails aligning single-wall carbon nanotube (SWNT) segments that are suspended in a fluid medium and then removing the aligned segments from suspension in a way that macroscopic, ordered assemblies of SWNT are formed. The invention is further directed to controlling the natural proclivity or nanotube segments to self assemble into or ordered structures by modifying the environment of the nanotubes and the history of that environment prior to and during the process. The materials and objects are “macroscopic” in that they are large enough to be seen without the aid of a microscope or of the dimensions of such objects. These macroscopic ordered SWNT materials and objects have the remarkable physical, electrical, and chemical properties that SWNT exhibit on the microscopic scale because they are comprised of nanotubes, each of which is aligned in the same direction and in contact with its nearest neighbors. An ordered assembly of closest SWNT also serves as a template for growth of more and larger ordered assemblies. An ordered assembly further serves as a foundation for post processing treatments that modify the assembly internally to specifically enhance selected material properties such as shear strength, tensile strength, compressive strength, toughness, electrical conductivity, and thermal conductivity.
