Abstract Invisible Ag-grid transparent electrode at a grid line width of 5 μm, spacing between the grid lines of 200 μm and a grid line thickness of 0.6 μm have been prepared on a 50 μm-thick flexible epoxy film substrate by a conventional gravure offset printing using our developed Ag nanoparticle ink. Furthermore, the Ag-grid were laminated with a poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) layer. Bending durabilities of the Ag-grid laminated with PEDOT:PSS (Ag-grid/PEDOT:PSS) transparent electrode were investigated via bending tests. The Ag-grid/PEDOT:PSS transparent electrode on the epoxy film substrate shows no noticeable resistance change throughout 20,000 outer bending cycles at a bending radius of 1.0 mm. The Ag-grid/PEDOT:PSS transparent electrode was applied to a commercial alternating-current powder electroluminescent device (ACPELD). Repeated bending durability of the fabricated ACPELD was investigated via a cyclic bending test. Luminance of the fabricated ACPELD is stable throughout the 30,000 outer bending cycles at a bending radius of 1.0 mm. The transparent electrode-based ACPELD develops also excellent bending durability.

粉末电致发光器件柔性环氧薄膜基板上印刷隐形银栅/PEDOT:PSS透明电极的弯曲可靠性

摘要 在 50 μm 厚的柔性环氧薄膜基板上，采用常规凹版胶印法制备了 5 μm 网格线宽、200 μm 网格线间距和 0.6 μm 网格线厚度的隐形银栅透明电极。使用我们开发的银纳米粒子墨水打印。此外，银网格与聚（3,4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT：PSS）层层压。通过弯曲试验研究了与 PEDOT:PSS (Ag-grid/PEDOT:PSS) 透明电极层压的 Ag 网格的弯曲耐久性。环氧树脂膜基板上的 Ag-grid/PEDOT:PSS 透明电极在弯曲半径为 1.0 mm 的情况下，在 20,000 次外部弯曲循环中没有显示出明显的电阻变化。Ag-grid/PEDOT：PSS透明电极应用于商用交流粉末电致发光器件（ACPELD）。通过循环弯曲试验研究了制造的 ACPELD 的重复弯曲耐久性。在弯曲半径为 1.0 mm 的情况下，制造的 ACPELD 的亮度在 30,000 次外部弯曲循环中是稳定的。基于透明电极的 ACPELD 也具有优异的弯曲耐久性。
