Positively-charged Reduced Graphene Oxide as an Adhesion Promoter for Highly-stable Silver Nanowire Film |
| 초록 |
In this manuscript, we demonstrated, for the first time, the atomically-thin conductive adhesion promoter of positively-charged reduced graphene oxide (rGO-NH3+) for transparent highly-stable AgNWs TCEs. The insertion of the rGO-NH3+ between AgNWs and polymeric substrate dramatically enhanced both chemical and mechanical stabilities of AgNWs. The AgNWs TCEs assisted with the adhesion promoter were extremely stable under harsh conditions including ultrasonication in various solvents, mechanical bending. This strong adhesion enhancement was originated from the charge transfer from the negatively-charged hydroxo- and oxo-groups onto AgNWs to the positively-charged protonated amine groups in rGO-NH3+, indicating the formation of ionic bonding. Notably, conductive rGO contributed a uniform current distribution of the mesh-type AgNWs. In addition, the 2D layered structure of atomically-thin rGO-NH3+ adhesion promoter could enhance the water protection properties of the AgNWs films. |
