Applied Nanotech announces carbon-nanotube composites
Applied Nanotech, US, has created carbon-nanotube composites for electron field emission applications that it says have significantly improved properties.
"In light of recent public comments from Mitsubishi, Noritake, Samsung, NHK and others stating that carbon-nanotube field emission is the future technology for large consumer television applications, our new composites will expedite the transition to production for manufacturers and facilitate new licensing agreements for us," said Zvi Yaniv, president of Applied Nanotech.
Applied Nanotech says that it was able to lower the voltage needed for optimal electron emission by combining the carbon nanotube composites with other conductive and non-conductive nanoparticles. Typically, a carbon nanotube needs to be in an electric field of at least 2.5 to 4.5 V/μm for field emission to take place. Applied Nanotech claims that its composites, on the other hand, have a threshold voltage of between 1.5 and 3 V/μm under the same conditions.
The company claims that this decrease in threshold voltage, along with the fact that the mixture contains fewer carbon nanotubes, may reduce material cost, enable the use of non-purified carbon nanotubes, allow the use of lower-cost electronic drivers and might not require processes that align the carbon nanotubes perpendicularly to the substrate.
Applied Nanotech is a subsidiary of SI Diamond.
