US Patent 7855496 - Boron nitride nanotube paste

Carbon nanotubes have been shown to exhibit superior electron emission properties but may have a short lifespan if they are in an oxygen environment. This patent from Samsung teaches an alternative electron emitting nanomaterials based on a boron nitride nanotube paste. Claim 1 reads:

1. A boron nitride nanotube paste composition comprising:

about 100 parts by weight boron nitride nanotubes;

from about 500 to about 2000 parts by weight glass frit;

from about 1000 to about 2000 parts by weight filler;

from about 2000 to about 4000 parts by weight organic solvent; and

from about 4000 to about 6000 parts by weight polymer binder.
