相对传统制备方法, 喷墨印刷作为一种低成本、直接图形化、无接触的薄膜沉积技术, 可将导电材料直接在衬底上图形化, 从而大幅节约时间和材料成本, 在柔性器件生产中显示出巨大的潜力。为了满足柔性电子低温制备的需求, 喷墨印刷制备柔性电极不仅要考虑高性能低温型导电墨水的制备, 还要关注烧结技术的低温应用。本文对柔性电极的喷墨印刷制备技术的研究进展进行了总结, 分别对导电材料和烧结技术的低温应用进行介绍并分析现阶段存在的问题, 并对喷墨印刷柔性电极的未来发展方向进行了展望。

Compared with traditional technology, inkjet printing as a cost effective, direct patterning and noncontact deposition technology, can be used to directly pattern conductive materials onto substrates leading to less process time and lower material cost, and shows incomparable potential in the manufacture of flexible electronic devices. To meet the demand of low-temperature manufacture of flexible electronic devices, not only the fabrication of low-temperature and high performance conductive materials but also the low-temperature applications of sintering technologies should be taken into consideration. This paper offers a retrospection of the research efforts in inkjet printing flexible electrodes, and provides elaborate descriptions about conductive materials and low-temperature applications of sintering technologies. The problems restricting the applications of different conductive materials and sintering technologies in flexible electrodes are paid attentions, and the future direction of inkjet printing flexible electrodes is pointed out.
