      :Silver nanowires have garnered a significant amount of research attention due to their excellent electrical, transmittance, flexible properties as well as the source of raw materials is wide and cheap, which are now regarded as the next generation of flexible transparent materials and have been used in the fields of solar cells, organic light-emitting diodes (OLEDs) and flexible liquid crystal displays (LCDs). The length and yield of silver nanowires synthesisd with traditional polyol process is lower, which is the major method for the synthesis of silver nanowires. For above background, to improve the length and yiled of silver nanowires, CuCl2 was used as the etching agent, which can prevent the oxidative etching, besides, temperature, polymer to AgNO3 ratio and CuCl2 amount were all considerable factors. The result show that the length of silver nanowires could grow to 60 μm when temperature was 160, PVP to AgNO3 molar ratio was 1.5, AgNO3 to CuCl2 molar ratio was 200, the yield of silver nanowires could over 80%.
