DETAILED DESCRIPTION - Graphene transparent conductive film on glass substrate is prepared by (A) selecting soda-lime glass and quartz glass with thickness of 2-3 mm, and cutting into small sheets with same sizes; (B) preparing graphene oxide powder; (C) preparing stable graphene suspension solution; (D) preparing cut sheet glasses; (E) preparing soaked sheet glasses; (G) drying glass by air; (H) under vacuum degree of 10-100 Pa, thermally treating graphene coated sheet glasses for 5-10 minutes at 300-500 degrees C, cooling sheet glass, coating and thermally treating glass. The step (B) comprises taking piece of graphite paper as anode, carbon rod as cathode, and 98% concentrated sulfuric acid as electrolyte; under a constant current of 0.2 A, oxidizing and stripping graphite paper for 20-30 hours, and diluting electrolyte with 10 times distilled water; after cooling solution to room temperature, separating solution by a high-speed centrifugal machine with speed of 12000 revolutions/minute (rpm) and filtering solution; fully washing filtered powder by distilled water until powder is neutral, and drying powder at 50-60 degrees C under vacuum degree of 10-100 Pa for obtaining graphene oxide powder. The step (C) comprises adding distilled water (100 mL) into graphene oxide powder (50-150 mg) for diluting powder; after ultrasonically dispersing powder, adding into hydrazine hydrate, where use amount is 20 mL of hydrazine hydrate in per g of graphene oxide powder; heating powder for 6-10 hours in constant-temperature water bath of 75-85 degrees C; and reducing powder for preparing stable graphene suspension solution (0.5-1.5 mg/mL). The step (D) comprises soaking cut sheet glasses by a mixed solution of 98% concentrated sulfuric acid and 30% hydrogen peroxide at vol. ratio of 7:3 for 2-4 hours at 70-90 degrees C, taking out sheet glasses, cleaning sheet glasses by deionized water and drying sheet glasses by nitrogen. The step (E) comprises soaking cleaned sheet glasses into 0.05-0.15 mol/L of 3-aminopropyl triethoxy silane ethanol solution for 30-90 minutes, after taking out, cleaning the sheet glasses by ethanol and drying the sheet glasses by nitrogen. The step (F) comprises drying sheet glasses with surfaces treated for 2-4 hours at 80-100 degrees C under vacuum degree of 10-100 Pa so that 3-aminopropyl triethoxy silane is completely concentrated on surface of the glass. The step (G) comprises soaking glass with surface modified into graphene suspension solution, vertically lifting glass at speed of 1-2 mm/s and naturally drying glass by air. The step (H) comprises under vacuum degree of 10-100 Pa, thermally treating graphene coated sheet glasses for 5-10 minutes at 300-500 degrees C, cooling sheet glass along furnace to room temperature, repeatedly coating and thermally treating glass for 15-20 times.
