摘　　要：本文通过液相化学还原和热还原联合作用制备了柔性透明导电石墨烯膜.阳极氧化铝(AAO)模板在制备过程中既作为抽滤的滤网,又作为热还原处理时支撑石墨烯膜的衬底,制成的柔性透明石墨烯膜对波长为540—840nm的可见光透光率为80%,面电阻为850Ω/平方,这与化学气相沉积法制备的石墨烯膜(280—770Ω/平方)相近,而低于溶液法制备的石墨烯膜(通常是103—104Ω/平方).A novel procedure {or producing flexible transparent conductive Graphene films was reported. The synthetic procedure includes a solution-processed chemical reduction and an anodized aluminum oxide （AAO） membrane filter assisted for thermal reduction. Final flexible transparent graphene films produced by this method exhibited the sheet resistance less than 850Ω/square with 80% transmittance under visible-light irradiation （wavelengths： 540-840 nm）. This sheet resistance value is close to that of the graphene films obtained from CVD method （280-770 Ω/square）, and is much lower than that of the graphene films obtained from solution process （usually, in 10a- 104 Ω/square）.
