Flexible transparent conductive film based on silver nanowires and reduced graphene oxide

【摘要】 Silver nanowires（Ag NWs）with diameter of 90—150 nm and length of 20—50μm were successfully synthesized by a polyol process.Graphene oxide（GO）was prepared by Hummers method,and was reduced with strong hydrazine hydrate at room temperature.The flexible transparent conductive films（TCFs）were fabricated using the mixed cellulose eater（MCE）as matrix and Ag NWs and reduced graphene oxide（r GO）as conductive fillers by the improved vacuum filtration process.Then,the optical,electrical and mechanical properties of the Ag NWs-r GO films were investigated.The results show that for the Ag NWs-r GO film produced with the deposition densities of Ag NWs and r GO as110 mg·m^-2 and 55 mg·m^-2,the optical transmission at 550 nm is 88.4%with Rs around 891Ω·sq^-1,whereas the optical transmission for the Ag NWs-r GO film with deposition densities of Ag NWs and r GO of 385 mg·m^-2 and 55 mg·m^-2 is79.0%at 550 nm with Rs around 9.6Ω·sq^-1.There is little overt increase in Rs of the Ag NWS-r GO film after tape tests for 200 times.The bending test results indicate that the change in Rs of Ag NWs-MCE film is less than 2%even after200 cycles of compressive or tensile bending.The excellent mechanical properties of the Ag NWs-r GO film can be attributed to the burying of Ag NWs and r GO at the surface of MCE.更多还原
