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: The structure for the double-sided transparent conductive films of AgNWs/PVC/AgNWs was designed as shown in Fig. 1 and achieved by the following steps. First, the AgNWs suspension was diluted to a concentration of 1 mg/mL and supersonic vibrated for 10–30 s. The PVC film was vertically fixed on the dip arm and moved down into the AgNWs suspension at a dipping speed of 40~70 mm/min. When the PVC substrate was wholly dipped into the suspension and held for 30 s, the PVC film began to move up to the air at a lifting speed of 80~110 mm/min and air dried naturally for 30 s. This down and up process was repeated for three times according to a set program. Whereafter, the wet AgNWs/PVC films were carefully dried in a drying oven at 80 °C for 10 min to remove the organic solvent. To avoid agglomeration, heat treatment should be applied uniformly to avoid uneven local heating and damage to the substrate. In order to increase the adhesion properties, the films were mechanically pressed at 3 MPa and 10 MPa for 20 s successively by using a mechanical tablet machine with a pressure gage and a stopwatch [30]. The first press at 3 MPa is aimed to prepress the AgNWs for a low resistance, and the second press is to enhance the conjunction between AgNWs and with substrate.Fig. 1
