    In this contribution, we present the impact of increasing humidity (0 %RH at 70 %RH (97 %RH) on amorphous cellulose thin films which serve as model systems for regenerated cellulose. The films were prepared by spin coating of two different trimethylsilyl cellulose precursors and converted to cellulose by simple hydrochloric acid vapor hydrolysis. Afterwards different physical treatments, such as swelling and drying, were performed and the consequences of the water vapor uptake were investigated. This process was examined in real time by XRR, GI-SAXS and QCM-D equipped with a humidity module to obtain information about changes of the thickness, roughness, electron density and pore size of the films.
