New applications for metal-polymer nanocomposites have emerged in the field of organic optics and electronics [1], or in the field of hybrid sensors [2]. Therefore, much effort has been put to better understand the growth process and structural transition of nanocomposites [3]. We investigated in situ the growth of a sputter-deposited ultra-thin gold film on top of a pre-structured colloidal polymer template using grazing incidence small-angle X-ray scattering (GISAXS). The underlying colloidal polymer template was deposited by using the novel technique of airbrush-spray coating, allowing for the installation of stripe-type trapezoidal pattern consisting of 3D hexagonally closed-packed colloids [4]. We present our findings on the formation of gold nanoclusters on top of the individual polymer colloids and give an outlook how to open a promising route to generate plasmon waveguides and photonic crystals, e.g. anti-reflective coatings.
