Nanostructured noble metal films on polymer layers promise various potentials applications in solar cells, biosensors, reflective or antireflective coatings. Moreover, such material combinations have recently gained importance for stabilizing thin polymer films during annealing above glass temperature. In order to study the effect of polymer film thickness dPS and molecular weight MW we combine sputter deposition with grazing incidence X-ray scattering (GISAXS) to investigate in-situ the growth kinetics of Au on polystyrene thin films with different thin (3-80nm) thicknesses and two different MWs (4 and 270kDa). We analyze quantitatively the metal nanoparticle layer growth and compare our results within the different polymer thicknesses. It is mandatory to understand the influence of the growth kinetics on the metal film morphology during sputter deposition for understanding the influence of MW and dPS on Au cluster growth. For future studies the results could be compared with different homopolymers.
