In this study, an additive-free transfer process is proposed for Ag nanowire (Ag NW)/PDMS transparent conductive films. Ag NW networks are first formed on high-wettability substrates and then transferred onto PDMS, with film structure and properties tuned by coating cycles, nanowire concentration, and substrate type. On low-concentration glass substrates, the coffee-ring effect reduces film uniformity, whereas high-thermal-conductivity aluminum substrates promote uniform network formation by enabling faster and more homogeneous solvent evaporation, mitigating performance degradation. Combining low-concentration multilayer coating with an Al substrate achieves a favorable balance between optical transparency and electrical conductivity, yielding a practical figure of merit (FoM) of approximately 100.
