Abstract

We developed and characterized inks based on dispersions of N-doped titanium dioxide (TiO2) in polyethylenimine (PEI)/ethanol solutions with chemicophysical properties suitable for the ink-jet printing process. In detail, we prepared suspensions by varying the concentration of the polymeric dispersant to investigate the effect of the dispersant on the time stability and printability of the ink. Moreover, we printed the N-doped TiO 2/PEI-based inks on different substrates and studied as the substrate temperature and the printing parameters influenced the printed product quality. Furthermore, the optical properties and the morphology of the printed films were also investigated. © 2011 Wiley Periodicals, Inc.
