Effect of Reduced-Graphene Oxide on Flexible Transparent Films Composed of Reduced Graphene Oxide and Silver Nanowires

Abstract:

We fabricated the flexible transparent conductive films composed of silver nanowires (AgNWs) and reduced graphene oxide (rGO) as hybrid transparent electrode and mixed cellulose eater (MCE) as substrate by vacuum-filtrating method. Effect of rGO on the electrical and optical and mechanical properties of flexible transparent films composed of rGO and AgNWs were studied. The results show that with rGO deposition density increase, the optical transmission at 550 nm has a little decrease, while the sheet resistance (Rs) gradually decrease. Tape tests up to 200 cycles and bending fatigue tests up to 200 cycles were performed by monitoring the in-situ resistance change. Film sustained excellent reliability of the AgNWs/rGO hybrid conductive networks, where the fractional resistance change is little overt increase after tape tests and less than 3% after bending test. The excellent mechanical properties of the AgNWs/rGO film can be attributed to the burying of the AgNWs and RGO film at the surface of MCEs.
