N2 - In electrospray printing, a plume of highly charged droplets is created from a conductive ink. Printing occurs by positioning a target substrate in the path of the emitted material. Here, the ink used is a colloidal dispersion consisting of nanoparticles suspended in a volatile solvent. The selection of a volatile solvent allows for rapid evaporation of the droplets in-flight to produce dry nanoparticles. An excess electric charge is imparted on the emitted particles during electrospray. The interaction of this charge with the global electric field and with other charged particles/ droplets governs the particles trajectory and determines the microstructure of the printed deposit. In this study, we characterized the structure of nanoparticle deposits printed using electrospray for short spray times. Electrospray printing is capable of exerting much finer control over microstructure compared to other printing techniques. This has significant implications for the manufacturing of thin-films.
