| 摘 要： | 提出了一种基于电场驱动喷射沉积微尺度3D打印制造高分辨率纸基电子的新方法。阐述了该方法的基本原理与工艺流程，通过实验揭示了主要工艺参数（电压、气压、打印速度）对三种纸质基材上打印银线的质量和精度影响及其规律。利用自主研发的电场驱动喷射微3D打印机，使用含银量75%和动力黏度35 Pa·s（25 ℃）的低温纳米银浆，并结合优化工艺窗口，在纸质基材上通过多层堆叠打印实现了高分辨率、大高宽比微纳结构，其中在RC相纸上堆积15层后，其线宽可保持在10 μm、高宽比增至6.33，电阻下降了94.8%。最后，在不同纸质基材表面制作了柔性电磁驱动器、复杂导电图案等样件来证明其打印能力。结果表明，采用电场驱动射流沉积微尺度3D打印技术新方法，并结合高黏度低温烧结纳米银浆，可为高性能纸基电子制造提供有效途径。

| Abstract: | A novel method of the electric-field-driven（EFD）jet deposition micro-scale 3D printing for fabricating high resolution circuit on paper-based surface was proposed. The basic principles and process flows of the proposed method were presented. The effects and rules of the main processing parameters（e. g.， the voltage， back pressure， printing speed） on the accuracy and quality of silver wires fabrications were revealed by a serial of experiments. Then， by using optimized parameters and the nano silver paste（75% silver content and 35 Pa·s（at 25 ℃）dynamic viscosity）， the micro/nano-scale structure with high resolution and high aspect ratio was fabricated by multi-layer stacking on three kinds of paper substrates. For example， the line width with 15 layers stacking on RC photo paper may be kept at 10 μm， and the aspect ratio may be increased to 6.33， causing the 94.8% decrease of the resistance. Finally， flexible electromagnetic actuators（FEMAs） and complex conductive patterns were fabricated on different paper substrates to prove the printing ability. The results show that the new method of EFD 3D printing technology combined with high viscosity and low temperature sintering nano silver paste may provide an effective way for high-performance paper-based electronics. |
