In this study, we present a scalable mechanochemical route for the exfoliation of graphite in a planetary ball mill with melamine to form melamine-intercalated graphene nanosheets (M-GNS). M-GNS morphology was evaluated, revealing small particles, down to 14 nm in diameter and 0.4 nm thick. The M-GNS were used as a functional material in the formulation of an inkjet-printable conductive ink, based on green solvents: water, ethanol, and ethylene glycol. The ink satisfied restrictions regarding stability and nanoparticle size; in addition, it was successfully inkjet printed on plastic sheets. Thermal and photonic post-print processing were evaluated as Nanomaterials (Basel, Switzerland)Conductive Inks Based on Melamine Intercalated Graphene Nanosheets for Inkjet Printed Flexible Electronics.PMC9457697PKP-2016-06-4480DOK-2021-02-2362UIP-2020-02-9139KK.01.1.1.01.0001Kralj MKrivacic SMarcius MZubak MKassal PIvanisevic IHalasz ISupina AfalseConductive Inks Based on Melamine Intercalated Graphene Nanosheets for Inkjet Printed Flexible Electronics.With the growing number of flexible electronics applications, environmentally benign ways of mass-producing graphene electronics are sought.
