以硝酸银溶液为前驱液体,聚酰亚胺(PI)薄膜为基材,采用静电热解和高频超声相结合的方法制备镀银导电薄膜。采用X射线衍射(XRD)、透射电子显微镜(TEM)、能谱仪(EDS)、原子力显微镜(AFM)、电阻测试仪等对制得的样品进行表征。结果显示:硝酸银(AgNO_3)为0.15mol/L、电压为20kV、基板和喷嘴距离为4cm、沉积时间30min、200℃退火时,制得的导电薄膜表面方阻低至1.4Ω。
Silver nitrate solution as the precursor liquid, polyimide (PI) film as the substrate, the use of electrostatic pyrolysis and high frequency ultrasonic method to prepare a silver-plated conductive film. The prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive spectrometer (EDS), atomic force microscopy (AFM) The results show that the surface resistivity of the conductive film is as low as 1.4Ω when the AgNO_3 is 0.15mol / L, the voltage is 20kV, the distance between the substrate and the nozzle is 4cm, the deposition time is 30min and the annealing temperature is 200 ℃.
