Data corresponds to the demonstration of photonic curing of graphene/nitrocellulose patterns, in which the exothermic decomposition of nitrocellulose modifies and aids the annealing reaction. Few-layer graphene flakes are produced by liquid-phase exfoliation and stabilized by nitrocellulose to formulate inks suitable for direct write printing. Graphene thin films exhibit high conductivity and mechanical flexibility following the photonic annealing step, along with a porous microstructure. Characterization of the materials using Raman spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, thermal gravimetric analysis, differential scanning calorimetry, and electrical measurements reveals suitable properties for application in printed and flexible electronics, with microsupercapacitors demonstrated leveraging the porous microstructure and process compatibility with paper and plastic substrates.
