Inkjet printing conductive ink was prepared with the as-prepared silver nanoparticles as conductive fillers and deionized water as the solvent and leveling agent (MY-3000) and silicone defoamer (NXZ) and wetting agent (TRITONX-405) and moisturizer (glycerol) as functional additives. We investigated the effects of viscosity and surface tension of conductive ink and the inkjet print parameters including number of nozzle, print speed, and ink droplet spacing on inkjet printability of conductive ink. The research results show that the inks with the viscosity range of 2.8–9.1 mPa·s and the surface tension of 33.4 mN·m⁻¹ are suitable for inkjet printing. The printing accuracy of the print pattern is related to the number of nozzles and droplet space and the printing layer, but not to the printing speed, but can be changed appropriately to improve the print efficiency. When the mass content of silver nanoparticles is 6.91 wt%, the sheet resistance of the printing pattern with four layers is 2.71 Ω·cm⁻¹, which is in appropriate printing conditions of the inkjet printing voltage of 21 V, printing speed of 60 m· S⁻¹, ink droplet space of 20 μm, and nozzles of 2. The systematic studies of printability and electrical conductivity of inkjet printing silver nanoparticles conductive ink prove the feasibility of the ink and provide some ideas for future applications.

以制备的银纳米颗粒为导电填料，用去离子水为溶剂和流平剂（MY-3000），有机硅消泡剂（NXZ）和润湿剂（TRITONX-405）和保湿剂（甘油）为制备的喷墨印刷导电油墨。功能添加剂。我们研究了导电油墨的粘度和表面张力以及喷墨打印参数（包括喷嘴数量，打印速度和墨滴间距）对导电油墨喷墨打印性能的影响。研究结果表明，该油墨的粘度范围为2.8–9.1 mPa·s，表面张力为33.4 mN·m ^-1适用于喷墨打印。印刷图案的印刷精度与喷嘴的数量和液滴空间以及印刷层有关，而与印刷速度无关，但是可以适当地改变以提高印刷效率。当银纳米颗粒的质量含量为6.91wt％时，四层印刷图案的薄层电阻为2.71Ω·cm ^-1，这在喷墨印刷电压为21V，印刷速度为60m的适当印刷条件下。 ·S ^-1，墨滴间距为20μm，喷嘴为2。对喷墨印刷银纳米粒子导电油墨的可印刷性和导电性的系统研究证明了该油墨的可行性，并为将来的应用提供了一些思路。
