Reporters obtained the following quote from the background information supplied by the inventors: "The invention relates generally to carbon nanotube films and, particularly, to a method for making a carbon nanotube film.
"Carbon nanotubes (CNTs) produced by means of arc discharge between graphite rods were first discovered and reported in an article by
"Carbon nanotube film has been found especially useful in field emission electron sources, photoelectric and biological sensors, transparent electrical conductors, battery electrodes, absorbing materials, water purification materials, light emitting material, and related devices. Thus, methods for making the carbon nanotube film have been become the basis for applications in the above-described fields. Currently, carbon nanotube film can be made by a method of direct growth.
"Moreover, the carbon nanotube film can also be made by methods using carbon nanotube powders, such as a dropping and drying solvent method, a Langmuir-blodgett (L-B) method, a printing method, an electrophoresis method, a membrane filter method, etc. However, the above-described methods generally have complicated fabrication procedures. Thus, in use, such methods have proven less efficient than truly desirable. Furthermore, the carbon nanotube films produced by the above-described methods have poor tensile strength and/or toughness. Thus, the carbon nanotube films are susceptible to fracture.
"What is needed, therefore, is a method for making a carbon nanotube film, that is very simple, efficient, and produces a film whose toughness is excellent."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "A method for making a carbon nanotube film includes the steps of: (a) adding a plurality of carbon nanotubes to a solvent to create a carbon nanotube floccule structure in the solvent; (b) separating the carbon nanotube floccule structure from the solvent; and © shaping the separated carbon nanotube floccule structure into the carbon nanotube film.
"Other advantages and novel features of the present method for making a carbon nanotube film will become more apparent from the following detailed description of presents embodiments when taken in conjunction with the accompanying drawings."
