Nanostructured polymer-metal-composite films show great perspectives for optoelectronic applications, e.g. as sensors or photovoltaics. To tailor properties of such devices the self-assembly process of the nanostructures needs to be understood. We studied in situ the evolution of the cluster growth morphology by grazing incidence small-angle X-ray scattering (GISAXS), the crystallinity of the nanogranular metal film with grazing incidence wide-angle X-ray scattering (GIWAXS) and the optical properties using surface differential reflectance spectroscopy (SDRS) all simultaneously during Al sputter deposition on nanostructured polymer templates. Our study reveals the selective decoration of Al on the polymer domains and the templates influence on the percolation behavior of the Al layer.
