| 中文摘要: |
| 以酒石酸银作为前驱体，1,2-丙二胺为络合剂，乙醇为溶剂制备无颗粒酒石酸银导电墨水。以丙烯酸乳液为原料制备模板，利用模板法和旋涂工艺法，在PET基材上制备透明导电银网格薄膜。采用X射线衍射(XRD)、扫描电子显微镜(SEM)、傅里叶红外光谱仪(FTIR)等方法对制备的导电墨水和透明导电银网格薄膜进行表征。结果表明，该方法实现了银网格完全嵌入在裂纹模板凹槽中，通过调控模板的线宽大小及网孔数量可获得透过率为82%、方阻为28 Ω/sq的银网格透明导电薄膜。该导电薄膜的薄膜电阻经过100次弯曲后没有明显的变化，可以有效克服ITO薄膜柔性差的缺点。 |
| 英文摘要: |
| A particle-free silver tartrate conductive ink was prepared by using silver tartrate as a precursor, 1,2-propylene diamine as a complexing agent and ethanol as a solvent. The template was prepared with acrylic emulsion as raw material, and the transparent conductive silver grid film was prepared on the PET substrate by the template method and spin coating process. The prepared conductive ink and transparent conductive silver network film were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared (FTIR) spectroscopy, etc. The results show that the silver grid is completely embedded in the groove of crack template, and that the transparent conductive silver grid film with transmittance of 82% and square resistance of 28 Ω/sq can be obtained by adjusting the line width and mesh number of the template. The film resistance of the conductive film does not change significantly after 100 times of bending, which effectively overcomes the poor flexibility of the ITO film. |
