Nanocomposites are important materials for a large variety of current applications like solar cells of hybrid and colloidal multilayer [Kaune] or waveguides [Maier] in optical circuits. For their efficient production in industrial processes it is mandatory to know, how the colloidal polymer layer influences the metal film morphology and the growth kinetics during sputter deposition. Commercial available monodispersed carboxylated polystyrene spheres (cPS) were employed to deposit opal crystals as templates on silicon wafer by using temperature controlled drop casting method. The GISAXS results revealing a delayed growth of a gold skin layer by evolution of the sphere form factors and the transmission signal vanishes simultaneously. This study is showing some hints that sputtered gold atoms can diffuse into the brush-like anionic surface of the cPS spheres before growing vertical on top.
