NOVELTY - A polyaniline nanowire array/three-dimensional graphene preparation and application method involves fill nickel nanowires into a circular ceramic mold and placing in the center of a high temperature tube furnace and heating under hydrogen/argon flow. The mold is annealed to obtain a three-dimensional nickel template, methane gas is passed for 10-20 minutes and the sample is cooled to room temperature under the hydrogen/argon gas flow to obtain a three-dimensional nickel sample of surface-deposited graphene. The obtained sample is placed in 3-5 mol/L hydrochloric acid etching nickel template to obtain three-dimensional graphene and immersed in concentrated nitric acid. Three-dimensional graphene is soaked in 1 mol/L sulfuric acid solution containing aniline, an equivalent volume 1 mol/L sulfuric acid solution containing ammonium persulfate is added, stirred well, reacted, washed the product and freeze-dried to obtain the polyaniline nanowire array/three-dimensional graphene. USE - Method for preparing a polyaniline nanowire array/three-dimensional graphene. ADVANTAGE - The method enables delaying the aging of the fermented baked noodle products by the synergistic action of various enzymes in the enzyme preparation and prolonging the preservation of the toasted bread of industrial large-scale processing. DETAILED DESCRIPTION - A polyaniline nanowire array/three-dimensional graphene preparing method involves filling 1.0 g nickel nanowires into a circular ceramic mold and placing in the center of a high temperature tube furnace and heating to 900-1100 degrees C under hydrogen/argon flow. The mold is annealed for 10-20 minutes to obtain a three-dimensional nickel template, methane gas is passed for 10-20 minutes and the sample is cooled to room temperature under the hydrogen/argon gas flow at a rate of 80-100 degrees C/minute to obtain a three-dimensional nickel sample of surface-deposited graphene. The obtained sample is placed in 3-5 mol/L hydrochloric acid etching nickel template to obtain three-dimensional graphene and immersed in concentrated nitric acid for 12-24 hours. Three-dimensional graphene is soaked in 1 mol/L sulfuric acid solution containing aniline for 3-5 hours, an equivalent volume 1 mol/L sulfuric acid solution containing ammonium persulfate is added, stirred well, reacted at 0 to -5 degrees C for 12-24 hours, washed the product and freeze-dried to obtain the polyaniline nanowire array/three-dimensional graphene.
