金属纳米粒子的喷墨打印直接形成金属导电线路,低成本、低消耗、工艺过程简单,是一个很具吸引力的方法。虽然目前大多数的研究集中在新金属方面,如金和银,但是本实验开发出一种廉价的导电材料作为替代品,即铜纳米粒子导电油墨。用多元醇过程制备出粒径为40nm～50nm的铜纳米粒子,把铜离子很好的分散在低粘度的导电油墨中。实验成功地演示了用铜导电油墨直接形成导电线路的方法。喷墨印刷形成的铜导电线路图形具有金属般的外观,并且在热处理后具有很好的导电性。薄膜在真空中以325℃的温度持续1h后,薄膜的电阻率达到17.2μΩ·cm。
Metal nanoparticle inkjet printing direct formation of metal conductive lines, low cost, low consumption, the process is simple, is an attractive method. Although most of the current research focuses on new metals such as gold and silver, this experiment developed an inexpensive conductive material as an alternative to copper nanoparticle conductive inks. Prepared by the polyol process the particle size of 40nm ~ 50nm copper nanoparticles, the copper ions well dispersed in the low viscosity of the conductive ink. The experiment successfully demonstrated the method of forming the conductive line directly with copper conductive ink. The copper conductive pattern formed by ink jet printing has a metallic appearance and has good conductivity after heat treatment. After the film was heated in vacuum at a temperature of 325 ° C for 1 hour, the resistivity of the film reached 17.2 μΩ · cm.
