Understanding the growth kinetics of metal polymer nanocomposites is of utmost importance to tailor the structure-function relationship for materials in modern technologies [1]. The key point during the processing of these nanocomposites is the interaction between the metal atoms and the underlying polymer layer(s) [2,3]. As sputter deposition is one of the most widely used industrial methods for rapid metal coating, we investigate the gold layer growth on top of a thin, spin-coated polystyrene film in-situ using microbeam grazing incidence small-angle x-ray scattering (µGISAXS) with high temporal resolution. We follow the different stages of nanoparticle formation from the initial correlated roughness changes induced by deposition to the fully established layer. We present the full morphological and structural characterization as function of deposition time and gold layer thickness.
