▎ 摘  要

NOVELTY - Preparation of flexible transparent polymer conductive thin film involves preparing stable colloidal dispersion of graphene oxide by Hmnmer's method, modifying graphene oxide surface using poly-diallyl dimethyl ammonium chloride, mixing sodium citrate and 0.01-0.5M silver nitrate solution in a three-necked flask, adding graphene oxide solution, 40 volume% poly diallyl dimethylammonium chloride solution and 40 volume% 4-5 ml TODA solution, mixing at room temperature under magnetic stirring at 130 degrees C for 12 hours, and then stirring in the dark. USE - Preparation of flexible transparent polymer conductive thin film used for biosensor and nano multi-field device. ADVANTAGE - The method efficiently and economically forms flexible transparent polymer conductive thin film having high antibacterial effect, conductivity and light transmittance. DETAILED DESCRIPTION - Preparation of flexible transparent polymer conductive thin film involves preparing stable colloidal dispersion of graphene oxide by Hmnmer's method, modifying graphene oxide surface using poly-diallyl dimethyl ammonium chloride, mixing sodium citrate and 0.01-0.5M silver nitrate solution in a three-necked flask, adding graphene oxide solution, 40 volume% poly diallyl dimethylammonium chloride solution and 40 volume% 4-5 ml TODA solution, mixing at room temperature under magnetic stirring at 130 degrees C for 12 hours, then stirring in the dark, reducing for 6-9 hours, washing and obtaining 1.02-1.5 mg/ml silver nanowire/graphene hybrid precursor solution, adding functionalized graphene solution as conductive filler and 40 ml alcohol solution of 20 %mass polyvinyl alcohol matrix, ultrasonically-agitating for 24-30 hours and obtaining polyvinyl acetate/graphene hybrid solution, pouring solution into a glass dish, processing at 40 degrees C for 72 hours, drying and forming film.
