In this study, we investigate the rheological properties as well as the stability and the electrical properties of inkjet inks based on silane-functionalized TiO2-particles. At first, we describe the preparation of the surface modified TiO2-particles, the formulation of the inks and the measurement procedures. The results of the measurements are presented and mechanisms, which could explain the observed characteristics, are discussed. Based on these findings, we discuss the limits of application of the surface modified nanoparticle inks for functional inkjet printing. Furthermore, we show the successful application of a surface modified nanoparticle ink for inkjet printing of photo electrodes for photo assisted water splitting.
