Description

The data corresponds to the demonstration of gravure-printed graphene patterns using polymer ethyl cellulose as an effective ink stabilizer. Concentrated graphene inks are prepared with controlled viscosity using the polymer as both stabilizing agent and rheology modifier. Gravure printing is demonstrated for high-fidelity patterns on flexible plastic substrates. Characterization of the printed patterns using optical microscopy, optical profilometry, atomic force microscopy, scanning electron microscopy, and electrical measurements reveals favorable properties for printed and flexible electronics applications.
