以柠檬酸银为导电金属前驱化合物,乙二醇单甲醚为保护性溶剂,单乙醇胺为络合剂,配置成无颗粒型导电银墨水。将导电银墨水旋涂在普通玻璃衬底上,在不同温度下退火处理形成银导电薄膜。其中通过250℃、20 min 退火处理形成的银薄膜颗粒均匀,成膜性较好,且电阻率为银体电阻典型值的2~4倍。在此基础上,采用 FujiFilm Dimatix DMP-2381材料打印机,在玻璃衬底上打印形成了导电性良好、线宽分别为100,200,300和400μm 的银线,方块电阻约为3Ω/□。

The silver conductive ink was prepared by dissolving silver citrate and monoethanolamine in 2-me-thoxyethanol.Silver citrate,2-methoxyethanol and monoethanolamine,were used as precursor metal com-pounds,protective solvent,and organic complexing agent,respectively.The silver films were synthesized on glass substrates through spin-coating followed by a post-annealing process.For the sample treated at 250 ℃ for 20 min,a high-quality silver film was formed with uniform grain size.The resistivity is about 2-4 times of the typical bulk value.Using the same prepared silver ink,conductive silver wires with widths of 100,200,300 and 400 μm,were printed with a FujiFilm Dimatix DMP 2381 inkjet printer,respectively.The printed silver wires have a sheet resistance of about 3 Ω/□.
