A hybrid transparent conductive films (TCFs) combining silver nanowires (AgNWs) and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) was fabricated using a piezoelectric dispenser printing method. The innovation lies in optimizing the ink composition and employing intense pulsed light sintering to enhance the TCF's performance. The optimized AgNW/PEDOT:PSS mixture, with an 8:2 ratio, achieved a figure of merit (FOM) of 28.05 × 10Ω, corresponding to a sheet resistance of 9.93 Ω sqand a transmittance of 88.0%. This represents a significant improvement over the pre-sintering FOM of 24.09 × 10Ω. Additionally, the hybrid TCFs exhibited outstanding structural stability, maintaining functionality after 7000 mechanical bending cycles. The results enable applications in flexible optoelectronic devices, and highlight the potential of this method to produce high-performance, flexible, and durable transparent electrodes, advancing the development of next-generation optoelectronic devices.
采用压电分配器印刷法制备了一种结合银纳米线（AgNWs）和聚（3,4-乙撑二氧噻吩）聚苯乙烯磺酸盐（PEDOT:PSS）的混合透明导电薄膜（TCFs）。创新之处在于优化油墨成分并采用强脉冲光烧结来提高TCF的性能。优化后的AgNW/PEDOT:PSS混合物比例为8:2，优值（FOM）达到28.05×10Ω，对应方阻为9.93Ω/sq，透过率为88.0%。这比烧结前的优值24.09×10Ω有了显著提高。此外，混合TCFs表现出出色的结构稳定性，在7000次机械弯曲循环后仍保持功能。这些结果使得其能够应用于柔性光电器件，并突出了该方法生产高性能、柔性和耐用透明电极的潜力，推动了下一代光电器件的发展。
