Abstract

We developed flexible and ultraviolet (UV)-curable electrodes with improved electrical conductivity using two light processes. Existing microparticle electrodes have poor durability. In this study, we improved electrode durability by facilitating UV light transmission using nanosilver particles and increased electrical conductivity using the photonic sintering process as a posttreatment process. The formulation of the UV-curable nanosilver paste developed this way had no problem in the cross-cut tape test and showed excellent pencil hardness (>3H). Furthermore, the electrical resistivity was 2.76 × 10⁻⁵ Ω·cm, and the resistance change rate was <1 % even after 50,000 times of repetitive tests with a 3-mm radius of curvature. When twelve electrode patterns with LED installation and bent were manufactured, we confirmed that there was no change in brightness. Finally, as polyethylene terephtalate, a low-temperature substrate, was not damaged even after the process was completed, the paste and process showed sufficient performance even in the low-temperature process.

基于UV和IPL光处理的高性能印刷电极，无需热处理

我们使用两种光工艺开发了具有改进导电性的柔性紫外线（UV）固化电极。现有的微粒电极具有较差的耐久性。在这项研究中，我们通过使用纳米银颗粒促进紫外光传输来提高电极的耐久性，并使用光子烧结工艺作为后处理工艺来提高电导率。以这种方式开发的UV可固化纳米银浆的配方在横切带测试中没有问题，并且显示出优异的铅笔硬度（>；3H）。电阻率为2.76×10−5Ω·cm，电阻变化率<；1%，即使在曲率半径为3mm的重复试验50000次之后。当制造出12个带有LED安装和弯曲的电极图案时，我们确认亮度没有变化。最后，由于聚乙烯对苯二甲酸酯是一种低温基材，即使在工艺完成后也没有损坏，因此即使在低温工艺中，浆料和工艺也表现出足够的性能。

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
