Polymer-metal nanocomposites are important materials for data storage, optical and electronic technologies. In combination with the wide variety of nanostructures offered by polymer materials in thin film technology, new routes for tailoring such nanocomposite devices are possible. Especially the use of colloidal nanoparticles is very attractive for magnetic data storage by ordering the colloidal nanoparticles. In our route to produce new colloidal polymer-metal nanocomposites, we combine the advantages of ordering colloidal thin films, polymer material characteristics and sputter deposition, leading to order on multiple length scales, from metal nanoparticle to large-scale domains. To understand the build-up of these multiple length scales, we use microbeam grazing incidence small angle x-ray scattering. We investigate IN-SITU the growth kinetics of magnetic and non-magnetic metals on colloidal polystyrene thin films as a function of the template treatment and present the resulting different growth regimes.
