Nanostructured polymer-metal-composite films demonstrate great perspectives for optoelectronic applications, e.g. as sensors or organic photovoltaics (OPV). To enhance properties of such devices the metal cluster self-assembly process needs to be understood. We correlate the emerging nanoscale morphologies with electronic properties and quantify the difference in silver growth, comparing the diblock copolymer template with its corresponding homopolymer thin film counterparts. In this contribution, we investigate the silver cluster morphology during the growth on a PMMA-b-P3HT diblock copolymer template. We applied with grazing incidence small-angle X-ray scattering (GISAXS) to observe the cluster formation. Our study reveals the selective wetting of silver on one of the polymer blocks and the influence of the template on the percolation behavior of the silver layer, which is measured with resistance measurements during the sputter deposition.
