Abstract Among the conventional metallic inks used in the printing process, silver exhibits high conductivity and thermal stability. Nevertheless, due to the high cost of silver, it cannot be extensively used for the fabrication of inks. As a competitive alternative, copper can be considered as a substitute for silver; however, copper ink oxidizes under certain atmospheric conditions. To meet these shortcomings, a cost effective, highly conductive, and oxidation-free copper-based ink has been synthesized in this study, wherein, oxidation of the copper particles in the copper-based ink was prevented by using copper complexes. The copper ink thus fabricated was printed on chemically treated Si/SiO2 substrates followed by the characterization of the printed copper films. The results of this study confirmed that the synthesized copper ink exhibited properties suitable for its use in the inkjet printing process for fabrication of various electronic devices.

铜油墨的合成与表征及用于电子设备的喷墨印刷铜图案的直接印刷

摘要 在印刷过程中使用的传统金属油墨中，银具有高导电性和热稳定性。然而，由于银的成本高，它不能广泛用于制造油墨。作为一种有竞争力的替代品，铜可以被视为银的替代品；然而，铜墨在某些大气条件下会氧化。为了克服这些缺点，本研究合成了一种具有成本效益、高导电性和无氧化的铜基油墨，其中通过使用铜配合物来防止铜基油墨中铜颗粒的氧化。将由此制造的铜油墨印刷在经过化学处理的 Si/SiO2 基材上，然后对印刷的铜膜进行表征。
