The method as claimed in claim 1, wherein sonicating the composite solution comprises sonicating at 50-90 * C to turn the color of the composite solution from brownish-yellow into deep brown. Previously presented
The method as claimed in claim 2, f ur ther comprising after removing the composite solution out of the 15 0 C water bath, sonicating the composite solution at 50-90 * C for 12-24 hours to turn the color of the composite solution from deep brown into black. Previously presented
The method as claimed in claim 1, wherein the surfactant is I-methy-2-pyrrolidone (NMP), isopropanol [[(NM P)]], propylene glycol methyl ether (PGME), ethyl acetate or methyl ethyl ketone (ME K). Currently amended
The method as claimed in claim 1, wherein the zeolite suspension further comprises a metal sa lt. Previously presented
The method as claimed in claim 5, wherein the metal salt is a salt of gold, platinum, silver, copper or nickel. Previously presented
The method as claimed in claim 1, further comprising before adding the surfactant, sonicating the composite solution for 1-3 hours. Previously presented
The method as claimed in claim 1, wherein treating the atomized droplets comprises using a gas to carry the atomized droplets through the plasma to charge the atomized droplets. Currently amended
The method as claimed in claim 8, wherein the gas is argon, helium or a mixed gas comprising argon and hydrogen. `i Li K Previously presented
Embodiments described in the patent, grouped by the materials and process steps they use.
5 materials1 process step
Zeolite suspension is prepared by mixing 16.04 g tetramethylammonium hydroxide (TMAOH) with 25.35 g pure water, adding 3.835 g aluminum isopropoxide and 6.009 g silicon dioxide, stirring for 24 hours, reacting in a sealed container at 92 °C for 48 hours, centrifuging at low speed (3000 rpm, 30 min) to remove large particles, then at high speed (12000 rpm, 30 min) to remove small particles. ~20 mL zeolite suspension is obtained at pH ~11.
2 materials1 process step
1 M aqueous solution of silver nitrate is added to the zeolite suspension to reach a weight ratio of 0.3% to introduce silver ions into the zeolite nanocrystals via ion exchange, increasing specific capacitance of the graphene composite film.
Layer stacks claimed or described, ordered top of device to substrate.
