Patent ID: 7118440

Claim:
A spray with a plurality of carbon nanotubes adopted for a cathode of an electronic device, comprising: a plurality of carbon nanotubes having a predetermined length; a solvent including Isoamyl Actrate, said solvent vaporizing within a range of predetermined temperatures to suspend the carbon nanotubes scattered therein; a binder including glass powder having particles of a first size arranged in the solvent, said binder having a predetermined adhesive characteristic with predetermined interfaces resulting from a predetermined adhesive process between the carbon nanotubes and a surface of the cathode of the electronic device; and an additive including a silver powder having silver particles of a second size, said additive reducing an impedance of the surface of the cathode of the electronic device; wherein the spray includes approximately 20–25 weight percents of the binding, approximately 10–18 weight percents of the additive, and approximately 5–10 weight percent of the carbon nanotubes, wherein the relationship between said predetermined length of the carbon nanotubes and said first size of the glass powder particles is approximately 10:9, and the relationship between said predetermined length of the carbon nanotubes and said second size of the silver particles is in the range between 10:3 and 10:5; wherein the solvent with the carbon nanotubes is sprayed on the surface of the cathode of the electronic device repeatedly, and vaporizes within the range of predetermined temperatures, and wherein after the predetermined adhesive process, the carbon nanotubes are dispersed on and adhesive to the surface of the cathode of the electronic device.
