Claim 10:
11. A method of forming a field emission material precursor, comprising:
introducing a plurality of carbon nanotubes into a liquid medium;
introducing a water stable conducting polymer into the liquid medium comprising the plurality of carbon nanotubes, wherein the plurality of carbon nanotubes is present at a particular ratio to a solution comprising the liquid medium and the polymer;
mixing the plurality of carbon nanotubes and the water stable conducting polymer in the liquid medium via an ultrasonic dispersion process at a power of greater than 1 W/cm2 and at a frequency of 20-50 kHz to form a base mixture;
introducing a metal oxide sol solution into the base mixture;
exposing the base mixture including the metal oxide sol solution to an ultrasonic dispersion process at a power of less than 1 W/cm2 and at a frequency of greater than 50 kHz to form a stable solution of a field emission material precursor; and
introducing a polar additive into the stable solution of the field emission material precursor to form a final field emission material precursor.
