ABSTRACT
Transparent conductive electrodes (TCEs) underpin modern optoelectronics, yet conventional indium–tin–oxide (ITO) coatings are brittle and require high temperature processing. Silver nanowire (AgNW) networks provide high conductance and transparency, but poor inter nanowire contact, oxidation and mechanical fragility limit their practical use. Graphene oxide (GO) and its reduced form (rGO) have emerged as low cost, two dimensional additives that can “solder” AgNW junctions and encapsulate networks to enhance conductivity and stability. This paper summarises the fabrication of solution processed AgNW/GO and AgNW/rGO composite TCEs. It covers the synthesis and characterisation of AgNWs, GO and rGO, composite film assembly, and the resulting optoelectronic, mechanical and environmental properties. Figures illustrate typical preparation routes, trends in sheet resistance and transmittance, mechanical endurance and the optimisation of GO treatment. The composite films exhibit sheet resistances as low as 14–18 Ω/sq with visible light transmittance approaching 87–88 %, enhanced bending durability and superior resistance to oxidation and halide corrosion. These attributes make the AgNW/GO platform promising for flexible displays, stretchable light emitting diodes and emerging wearable sensors.
