A Novel Method of Synthesizing Reduced Graphene Oxide from Paper Using Gas Plasma Jet

We present a novel, eco- friendly, and low-cost method for synthesizing reduced graphene oxide (rGO) from filter paper using an atmospheric argon plasma jet (APJ) powered by a simple Slayer Exciter circuit. This single-step approach, using boron-based solutions and IPA on filter paper upon exposure to APJ exposure, produces rGO with enhanced conductivity of about 172 S/m. The rGO films were characterized using TEM, Raman spectroscopy, and XRD which confirmed the formation ofrGO. This process enables an efficient approach for patterning conductive paths for paper-based circuits and for developing rGO-based flexible circuits.
