Nanostructures formed in a titanium dioxide (TiO 2 )–poly(styrene)‐block‐poly(ethyleneoxide) nanocomposite film on top of fluor‐doped tin oxide (FTO) layers are investigated. The combinatorial approach is based on probing a wedge‐shaped FTO‐gradient with grazing incidence small angle X‐ray scattering (GISAXS) in combination with a moderate micro‐focus X‐ray beam. The characteristic lateral length is given by adjacent nanowire‐shaped TiO 2 regions. It decreases from 200 nm on the thick FTO layer to 90 nm on the bare glass surface.Sketch of the FTO gradient coated with a nanocomposite layer probed in the combinatorial approach.
