A rapid low-cost technology to produce highly conductive laser-scribed reduced-graphene oxide (rGO) thin films on flexible substrates is developed. Isolated rGO films, up to 30 nm thick and with a conductivity of 102 S m−1 are produced at room temperature in a three-step process: filtering the graphene oxide (GO) solution through nitrocellulose membranes, reduction of GO surface using a DVD-burner laser and solvent-free transfer of the resulting rGO pattern onto new substrates via pressure-based mechanism. The loss of density in the reduced part produces an increase in the thickness enabling the transfer of rGO only. The rGO is characterized with several analytical techniques, and its reduction degree, thickness, morphology, electrochemical and electromechanical properties are investigated and optimized. The validation of the technology is tested using a wide variety of substrates, and its applicability as a sensing platform for dopamine detection and back electrode in an electroluminescent lamp is demonstrated, opening the venue for a plethora of other new applications.
