Lignin is a binding agent in wood and very promissing regarding the sustainable development of new bio-based applications. Therefore, three different lignins were tested for spray coating. The lignin was dissolved in two different solvent mainly in Aceton and Tetrahydrofuran. The structure and morphology as well as the crystallinity of the lignin thin films were investigated by using grazing incidence small-angle and wide-angle X-ray scattering (GISAXS/GIWAXS). Through atomic force microscopy (AFM) the surface morphology and film thickness were characterized. The first goal is to discover possible applications of lignin in thin film applications by the usage of spray coating. The second one is to characterize the moleculare and nonoscale arrangment of lignin in thin films.
