Bottom Line: The double-sided transparent conductive films of AgNWs/PVC/AgNWs using the silver nanowires and PVC substrate were fabricated by the dip-coating process followed by mechanical press treatment.The results indicate that the structure and photoelectric performances of the AgNWs films were mainly affected by the dipping and lifting speeds.At the optimized dipping speed of 50 mm/min and lifting speed of 100 mm/min, the AgNWs are evenly distributed on the surface of the PVC substrate, and the sheet resistance of AgNWs film on both sides of PVC is about 60 Ω/sq, and the optical transmittance is 84.55 % with the figure of merit value up to 35.8.

ABSTRACT
The double-sided transparent conductive films of AgNWs/PVC/AgNWs using the silver nanowires and PVC substrate were fabricated by the dip-coating process followed by mechanical press treatment. The morphological and structural characteristics were investigated by scanning electron microscope (SEM) and atomic force microscope (AFM), the photoelectric properties and mechanical stability were measured by ultraviolet-visible spectroscopy (UV-vis) spectrophotometer, four-point probe technique, 3M sticky tape test, and cyclic bending test. The results indicate that the structure and photoelectric performances of the AgNWs films were mainly affected by the dipping and lifting speeds. At the optimized dipping speed of 50 mm/min and lifting speed of 100 mm/min, the AgNWs are evenly distributed on the surface of the PVC substrate, and the sheet resistance of AgNWs film on both sides of PVC is about 60 Ω/sq, and the optical transmittance is 84.55 % with the figure of merit value up to 35.8. The film treated with the 10 MPa pressure shows excellent adhesion and low surface roughness of 17.8 nm and maintains its conductivity with the sheet resistance change of 17 % over 10,000 cyclic bends.

Mentions: This photoelectric phenomenon of AgNWs network can be explained by the difference of their microstructure. Figure 2 presents the SEM images of AgNWs films (Side 1) fabricated by the dip-coating process with different dipping speed and lifting speed. From Fig. 2, it can be seen that the dipping speed and lifting speed also has great influence on the structure of the films. When the dipping speed is 40 mm/min and lifting speed is 100 mm/min, it shows that the PVC substrate is wholly covered with AgNWs, but in some areas, there appear some congestion of AgNWs as shown by red arrows in Fig. 2a. This microstructure can make the film have a low resistance but will influence the optical transmittance. While seen from Fig. 2b, the AgNWs film fabricated at a dipping speed of 50 mm/min and lifting speed of 100 mm/min clearly shows that the AgNWs are evenly distributed on the surface of PVC substrate without any congestion, which makes the film have high transmittance and low resistance at the same time. However, when the dipping speed increases to 60 mm/min or 70 mm/min and the lifting speed is 100 mm/min, the AgNWs are poorly distributed on the substrate, forming some congestion and open space as shown by yellow arrows in Fig. 2c, d, which may be caused by the fluctuation of the suspension when using too high speed. This open space can increase the light transmittance to some degree but conversely destroy the continuity of AgNWs network and result in the increase of resistance.Fig. 2
