Description
Summary:We report the development and characterization of dielectric inks based on dispersions of TiO(2) in poly(ethylenimine)/ethanol solutions having physicochemical properties suitable to ink-jet printing process. In order to study the effect of polymer dispersant on the printability and stability of inks, we carried out dynamic light scattering analysis of different inks made with and without polymer. Moreover, we compare the curve of distribution of TiO(2) particles size at different aging times. For TiO2polymerwe optimize the inkjet parameters (amplitude and duration of jetting impulse, jetting frequency, substrate velocity) to obtain thin lines based on TiO(2)/poly(ethylenimine) nanocomposite on silicon substrate. Finally, the morphology of films was also investigated.
