将自制的纳米铜粉作为导电墨水的导电填料，通过添加一定量的分散剂、表面活性剂等其他助剂，超声波粉碎后制得纳米铜导电墨水。结果表明：随着固含量的增加，超声波分散时间越长，墨水的黏度越大。但电导率与超声波分散时间并无直接关系。随着固含量和烧结温度的增加，导电薄膜变得更致密、平整，电阻率逐渐降低。经过300℃烧结后电阻率可减至9.4×10–3Ω·cm。

The nano copper conductive ink was made from self-made nano copper powder as conductive filler broken by ultrasonic wave, added some dispersion agent and surface active agent. The results show that increasing solid content increase ultrasonic wave dispersion time and viscosity of the ink. But the conductivity is not directly dependent on ultrasonic wave dispersion time. With the increasing of solid content and sintering temperature, the conductive film become compact and smooth and its resistivity decreases. Its resistivity could fall to 9.4×10–3Ω?cm after sintering at 300℃.
