| Transparent conductive film materials have drawn much attention in the fields of the opto-electric devices, such as organic solar cells, organic light emitting diodes,or touch screens. In recent years, due to the inherent low resistivity of silver metal and the narrow width of silver nanowires, the percolation network of silver nanowires(Ag NWs) has several advantages, namely transmittance, high conductivity, well stability cost-effectiveness, easily prepared, feasibility of mass production and flexible, which is comparable to an ITO electrode. Therefore, AgNW network transparent conductive film can be readily prepared on substrates through brush, spray, wire-wound rod, or spin coating methods.In this paper, PEDOT:PSS/Ag NW, PEDOT:PSS/Ag NW/PEDOT:PSS hybrid films were prepared. The optical transmittance, sheet resistance, crystallization and surface morphology were characterized by using the double beam spectrophotometer, Hall Effect system, X-ray diffractometer and field emission scanning electron microscopy. Its main idea is as follows:(1) In this paper, PEDOT:PSS/Ag NW hybrid films were deposited on PET substrates by spin coating technique. The effects of spining cycles of Ag NW layer and PEDOT:PSS layer on the optical, electrical, structural surface morphology properties of the PEDOT:PSS/Ag NW hybrid films were investigated, respectively.(2) PEDOT:PSS/Ag NW/PEDOT:PSS hybrid films were deposited on PET substrates by spin coating technique. In this paper, the effects of PEDOT:PSS protective layer on crystallization, surface morphology, optical and electrical properties of the hybrid films are investigated. Effect of annealing temperature and holding time on electrical property of hybrid films were studied.(3) PEDOT:PSS/Ag NW/ITO hybrid films were deposited by spin coating and DC magnetron sputtering technique. The effects of spining cycles of Ag NW layer and ITO thickness on optical, electrical, crystallization and surface morphology properties of the hybrid films are investigated. |
