Abstract:

The present thesis explores the utilization of spray coating for the sustainable fabrication of cellulose-based organic electronics in the framework of four different studies. The scope of this work is to contribute to the ongoing green transformation of our society in the context of industrial processing, responsible production, and clean energy. In this regard, spray coating was applied as a low-cost, fast, and industrially relevant technique for both the production as well as the quality enhancement of functional organic polymer films. In addition to that, wood-based nanocellulose, a non-toxic and biodegradable polymer, was used to replace synthetic polymers as transparent, flexible matrix- and substrate material, and as dispersing agent for the fabrication of highly conductive electrodes. Finally, spray solvents were evaluated regarding their sustainability, industrial fitness, and thus suitability for the large-scale production of organic electronics. In the course of this, various kinds of functional, hybrid organic films and foils were fabricated. Their properties were correlated with their respective structure and morphology, with a special focus on surface-sensitive analysis techniques, namely grazing incidence X-ray scattering, atomic force microscopy, scanning electron microscopy, and sheet resistance measurements.
