A highly electrically conductive graphene-silver na no wire hybrid nanomaterial for transparent conductive films

摘要

Uniform and high-quality graphene oxide thin films were prepared using a dip-coating approach and were reduced to highly electrically conductive graphene nanosheet (GN) transparent conductive films (TCFs) using hydriodic acid. Silver nanowires (AgNWs), which were modified using thiophenol and exhibited a high aspect ratio and high electrical conductivity, were deposited on the surfaces of the GN TCFs through π-π interactions between the aromatic functional groups on the AgNWs and GNs to form high-performance GN/AgNW TCFs. The GN/AgNW hybrid nanomaterial films exhibited a sheet resistance of 71 Ω □~(-1) and 85% light transmittance.
