摘　　要：气溶胶喷印水性功能油墨能为微纳柔性电子技术提供更环保的解决方案,但在油墨特性及复杂的打印参数共同作用下,其打印连续性、迹线成形、过度喷涂方面的缺陷亟待解决。基于聚乙烯吡咯烷酮(PVP)水性油墨,通过控制变量法系统地探究了适用于气溶胶喷印的水性油墨黏度(1~10 mPa·s)并优化了喷印工艺,总结出水性油墨黏度与气溶胶喷印的最优参数范围设置规律,并据此进行了水性纳米银油墨的喷印,制备了外径为1.96 mm的平面螺旋电感,表征了其电感及品质因数,测试结果与仿真结果有良好的一致性,其电感在0.024μH左右,可应用于射频识别(RFID)、滤波以及感应元件等领域。该结果为气溶胶喷印水性功能油墨的研究提供了前期的实验支持,有望推动气溶胶喷印在微纳柔性电子技术中的发展。Aerosol jet printing of water-based functional ink offers a more environmentally solution for micro-nano flexible electronic technology.However,defects in printing continuity,trace formation,and excessive spraying urgently need resolution due to the interplay of ink characteristics and complex printing parameters.Based on water-based polyvinylpyrrolidone(PVP)ink,a controlled variable approach was employed to systematically investigate water-based ink viscosity suitable for aerosol jet printing(1-10 mPa·s),and the jet printing process was optimized.The regular setting range of optimal parameters for water-based ink viscosity and aerosol jet printing were summarized.According to the setting regularity,water-based nano-silver ink was jet-printed,and a planar spiral inductor with an outer diameter of 1.96 mm was prepared.The inductance and quality factor were characterized,showing good consistency between test and simulation results.With an inductance of around 0.024μH,it can be applied in fields of radio frequency identification(RFID),filtering,sensing components,etc.The results provide preliminary experimental support for the research of aerosol jet printing of water-based functional ink,promising the development of aerosol jet printing in micro-nano flexible electronic technology.
