Electrical conductivity and optical properties of water-based graphene/AgNWs hybrid inks for flexible electronics

The present study provides the description of water-based inks made of hybrid graphene-silver nanoparticles conductive fillers in a wide concentration range for printed electronics applications. Aqueous graphene suspensions were manufactured via ultrasonic exfoliation of pristine graphite, whereas polyol synthesis was used to obtain silver nanowires. Hybrid suspensions were centrifuged to improve transmittance while retaining electrical conductivity. As a result, we successfully manufactured conductive transparent films with transmittance up to 96%.
