The invention discloses a graphene conductive thin film used for a touch screen. The graphene conductive thin film is prepared from the following raw materials in parts by weight: 110-120 parts of polytetrafluoroethylene, 10-13 parts of conductive graphite solution, 20-30 parts of acrylamide, 0.1-0.2 parts of ethylene thiourea, 0.7-1 parts of sodium persulfate, 1-2 parts of glyceryl tristearate, 0.7-1 parts of trimethylolpropane, 1-2 parts of calcium stearate, and 0.6-1 parts of 8-hydroxyquinoline. The thin film is high in conductivity, uniform stability and quality, without causing the phenomena of bubble forming and the like when the thin film is used on the touch screen. 本发明公开了种触摸屏用石墨烯导电薄膜，它是由下述重量份的原料组成的：聚四氟乙烯110-120、导电石墨溶液10-13、丙烯酰胺20-30、乙撑硫脲0.1-0.2、过硫酸钠0.7-1、三硬脂酸甘油酯1-2、三羟甲基丙烷0.7-1、硬脂酸钙1-2、8-羟基喹啉0.6-1,本发明的薄膜导电性好，薄膜的均匀稳定性好，用在触摸屏上不会出现起泡等现象，薄膜品质高。
