透明导电薄膜(TCF)由于其兼具较高的透光度和较低的电阻率,被广泛应用在太阳电池、传感器和柔性有机发光二极管(OLED)等光电子器件中,制备高性能的TCF对其应用至关重要。采用胶束软模板法成功制备出一维的聚(3,4-乙烯二氧噻吩)纳米线(PEDOT NW),并与丹宁酸功能化碳纳米管(TCNT)相结合,通过喷涂法得到TCNT/PEDOT NW-聚对苯二甲酸乙二醇酯(PET)透明导电薄膜。结果表明:该薄膜在透光度为80.9%时,方块电阻为594.8Ω/□。随后,以该薄膜作为阳极制备出柔性OLED器件,该器件在电压为6.5 V时最高亮度为2 580 cd/m2;在电压为5 V时最高电流效率为1.612 7 cd/A,显示出其在光电子设备领域较大的应用潜力。
Abstract:Due to high transmittance and low resistivity, transparent conductive films(TCFs) are widely used in solar cells, sensors, flexible organic light emitting diodes(OLEDs) and other optoelectronic devices, and the preparation of high-performance TCFs is very important for their applications. One-dimensional poly(3,4-ethylenedioxythiophene) nanowires(PEDOT NWs) were successfully prepared by the micellar soft templating method, and combined with tannin-functionalized carbon nanotubes(TCNTs), TCNT/PEDOT NW-polyethylene terephthalate(PET) transparent conductive film was prepared by spraying process. The results show that when the transmittance of the film is 80.9%, the sheet resistance is 594.8 Ω/□. Subsequently, the film was used as an anode to fabricate a flexible OLED device. The device has a maximum brightness of 2 580 cd/m2 at a voltage of 6.5 V and a maximum current efficiency of 1.612 7 cd/A at a voltage of 5 V, showing its great application potential in the field of optoelectronic equipment.
