▎ 摘　　要

Strongly adhesive and highly stable transparent electrodes based on graphene and silver nanowires (AgNWs) have been developed by embedding biocompatible polylactic acid (PLA) between them. In the process of fabrication of such electrode, instead of removing the supporting PLA layer, this biocompatible polymer layer is sandwiched between graphene and AgNWs, thus simplifying the technology process. In comparison with the traditional graphene/AgNWs hybrid electrode, this novel hybrid electrode exhibits similar optical and electrical properties (around 84.0% at 550 nm, sheet resistance is 13.6 Omega/sq). Remarkably, the surface topography and mechanical flexibility of hybrid film is greatly enhanced due to the introduction of PLA layer. In addition to these, the PLA layer could also provide extra protection to AgNWs locating at the bottom as well as enhanced adhesion force to the substrate, thereby yielding outstanding chemical and electrical stability of the hybrid film. To demonstrate the potential application of the hybrid electrode, a pressure-addressing/electric-erasing liquid crystal device has been constructed, which shows a comfortable optical-electric performance. The strategy demonstrated here could contribute to strong adhesive and highly stable transparent electrodes in flexible optoelectronic devices. (C) 2016 Elsevier B.V. All rights reserved.
