Spray with carbon nanotubes and method to spray the same

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.
