摘　　要： 利用旋涂法和机械转移法在柔性衬底聚对苯二甲酸乙二酯(PET)基板表面构建石墨烯/银纳米线复合透明导电薄膜。复合薄膜具有优良的电学性能,在可见光550 nm处透过率为73.2%,薄膜面电阻低至0.32Ω/□。与银纳米线薄膜相比,石墨烯/银纳米线复合薄膜还表现出良好的电学稳定性,在90天后银纳米线薄膜面电阻增加率高达648%,而复合薄膜面电阻的增加率仅为30%。此外,在270天后,复合薄膜在循环弯曲300次前后,与LED灯串联可获得恒定的输出电压,表现出良好的机械弯曲稳定性。 The paper reports the fabrication of graphene / silver nanowire transparent conductive composite film on flexible polyethylene terephthalate( PET) substrate by spin-coating and mechanical transfer technique. The composite film has a sheet resistance of 0. 32 Ω / □ with 73. 2% transmittance at 550 nm,exhibiting excellent conductivity. The sheet resistance of silver nanowire film was increased up to648% for the duration of 90 days. In contrast,the sheet resistance of the graphene / silver nanowire composite film was slightly increased 30%. That confirms that the composite film show better electrical stability than silver naowire film at room temperature. Additionally,after the storage for 270 days,the constant output voltage can be obtained when the composite film before and after 300 bending cycles is used in series with the LED lamp,demonstrating the excellent mechanical stability of the composite film.
