    摘要:

    为适应电致变色领域越来越丰富的柔性化需求,解决柔性基底上直接制备电致变色薄膜性能不佳的问题。以聚对苯二甲酸乙二醇酯(PET)/银纳米线(AgNWs)为基底,采用室温直流反应磁控溅射制备了氧化铟锡(ITO)/氧化钨(WO3)薄膜,研究了AgNWs/ITO复合电极的光电性能以及PET/AgNWs/ITO/WO3薄膜的电致变色性能。结果表明,通过加镀ITO过渡层,克服了PET/AgNWs/WO3薄膜存在的着色不均匀、单次循环后性能迅速衰退等问题。最终获得了透过率调制为57.4%(550 nm处)、69.6%(1 000 nm处),着褪色响应时间分别为10.4 s和9.9 s,相应的着褪色效率分别为27.79 cm2/C和40.45 cm2/C的高性能柔性电致变色薄膜。薄膜在超过500次循环稳定测试以及2 000次弯折测试后仍能保证较高的透过率调制,展现出了在柔性电致变色领域的巨大应用潜力。

    Abstract:

    To solve the problem of poor performance of electrochromic films,which is the critical problem of electrochromic devices adapting to the current demand,the indium-tin oxide (ITO)/tungsten oxide (WO3) films were prepared at room temperature by DC reactive magnetron sputtering on the polyethylene terephthalate (PET)/silver nanowire (AgNWs).The photoelectric properties of AgNWs/ITO composite electrodes and the electrochromic properties of PET/AgNWs/ITO/WO3 films were investigated. The results show that the sheet resistance of the ITO-compositing electrode is significantly lower than that of AgNWs electrode,and the surface is more uniform and smoother.Thereby it overcomes the uneven coloring and rapid performance degradation after a single cycle of the WO3 film.The transmittance modulation of the flexible electrochromic film is 57.4% (at 550 nm) and 69.6% (at 1 000 nm),the colored and bleached response time is 10.4 s and 9.9 s,while the corresponding colored and bleached efficiency is 27.79 cm2/C and 40.45 cm2/C,respectively.In addition,the film can still maintain high transmittance modulation after more than 500 cycle stability tests and 2 000 bending tests,showing great application potential in the field of flexible electrochromic.
