以微米级铜粉为导电填料、酚醛树脂为粘接剂制备了导电油墨，并将该油墨以聚酰亚胺薄膜为基底，采用丝网印刷技术制备导电涂层。研究了铜粉添加量对铜酚醛树脂导电油墨的黏度、固含量以及导电涂层的微观形貌、电阻率和附着力的影响。研究表明，当铜粉添加量质量分数为70%时，制备的铜酚醛树脂导电油墨具有良好的性能，该导电油墨经丝网印刷得到的导电铜膜经低温固化后具有良好的电性能，其电阻率最低可以达到53.865×10–3Ω·cm。

The copper conductive ink was prepared by using the micron copper powder as the filler and phenolic resin as the adhesive, it was printed on the polyimide film by using the screen printing method. The effects of the copper content on the viscosity, solid content of copper conductive ink, microstructure, resistivity and adhesion of the conductive coating were studied. The results show that when the mass fraction of copper powder is 70%in the copper ink, by screen printing method, the conductive film which cures at low temperature presents good electric performances, whose lowest resistivity reaches 53.865×10–3Ω·cm.
