The fabrication of sustainable, thin, and flexible electrical devices on an industrial scale will be an important challenge in the future. Nanocomposites, consisting of conductive nanoparticles like silver nanowires (AgNWs) and a sustainable matrix material like cellulose nanofibrils (CNFs), can meet these requirements. Here, we report on the nanoscale structure and the corresponding optoelectronic properties of a sprayed CNFs-AgNWs nanocomposite electrode. Adding CNF to the aqueous AgNW-based spray ink improves the dispersion and distribution of the AgNWs. This, and the cold-welding of the AgNW junctions enhance the conductivity of the electrode greatly. Finally, we demonstrate the electrode's high transmittance, resilience under multiple cycles of bending deformations, and its long-term stability.
