Data corresponds to the demonstration of inkjet-printed graphene patterns using the polymer nitrocellulose as an effective ink stabilizer. Few-layer graphene flakes are produced by liquid-phase exfoliation and stabilized by nitrocellulose to formulate inks suitable for inkjet printing, blade coating, and spray coating. Graphene thin films exhibit high conductivity and mechanical flexibility following a thermal annealing step. Characterization of the materials using atomic force microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, thermal gravimetric analysis, and electrical measurements reveals suitable properties for application in printed and flexible electronics, with environmental and water immersion tests showing robust stability.
