Summary: Inorganic‐organic hybrid polymer sols where modified with differently prepared as well as commercial titania nanoparticles, to obtain coatings exhibiting a photo‐catalytic activity for the development of self‐cleaning textiles. The particles synthesized using a sol‐gel‐approach where, amongst others, investigated by XRD to prove the existence of titania crystallized in the anatase structure. The photo‐catalytic activity of the different particles as well of the coatings was compared by the decomposition of astrazone red induced by an irradiation with artificial and solar UV‐radiation. With respect to the underlying aim of the investigation the durability of the effect against washing was tested by standardized washing experiments, showing promising results.
