Deposition and characterization of silver nanowires embedded PEDOT:PSS thin films via electrohydrodynamic atomization

Silver nanowires (AgNWs) embedded PEDOT:PSS nanocomposite thin films was deposited on flexible substrate through electrohydrodynamic atomization technique. The optimization of flow rate and applied potential for achieving uniform thin film via Taylor cone formation has been discussed in detail. The crystallinity and surface morphology of the as-deposited thin films was investigated by X-ray diffraction and field emission scanning electron microscope. The X-ray photoelectron spectroscopy results showed that the nature of chemical bonding and film purity of intercalated AgNWs in PEDOT:PSS matrix. The optical and electrical studies revealed high transparency in the visible region and lower sheet resistance of the AgNWs/PEDOT:PSS thin films. These results indicate that the AgNWs embedded PEDOT:PSS is a key factor to enhance the film conductivity without any loss of optical properties which may create new horizon in their potential applications in optoelectronics.
