Abstract

Long-range interface correlations in nanocomposite films of a diblock copolymer matrix with embedded magnetic nanoparticles are investigated. A film thickness gradient representing a combinatorial approach to probe samples with different thicknesses prepared under identical conditions is addressed. Maghemite (F2O3) nanoparticles covered with polystyrene chains are incorporated in a thin film gradient of polystyrene-block- polyisoprene. The gradient is investigated with scanning micro-focus grazing incident small angle X-ray scattering (μGISAXS). The substrate surface roughness is imposed to the composite film surface resulting in roughness correlation. With decreasing film thickness this long-range interface correlation decays.
