Investigations on reduced graphene oxide film embedded with silver nanowire as a transparent conducting electrode

摘要

A simple and effective transparent conducting electrodes (TCEs) based on reduced graphene oxide film embedded with silver nanowire-(AgNW-rGO) was developed. The AgNW-rGO hybrid electrode was fabricated by using a simple and scalable dip-coating method. This solution processed TCEs showed high electrical conductivity when compared with pristine AgNW. AgNW-rGO TCEs also exhibited better stability than the pristine AgNW film when exposed to the ambient atmosphere. The electrical conductivity is found to increase by 4-fold with increase in the number of dipping cycles of AgNW after coating the graphene oxide (GO). This increase in the observed conductivity is attributed to the gas-barrier property of GO. AgNW/rGO TCEs exhibited a sheet resistance of 27 Ω/? with transparency=72% at 550 nm.
