For many applications, mesoporous titania nanostructures are exposed to water or need to be backfilled via infiltration with an aqueous solution, which can cause deformations of the nanostructure by capillary forces. In this work, the degree of deformation caused by water infiltration in two types of mesoporous, nanostructured titania films exposed to water vapor is compared. The different types of...
Thin blend films of the diblock copolymer poly(3-hexylthiophene-2,5-diyl)-block-polystyrene (P3HT-b-PS) and phenyl-C61-butyric acid methyl ester (PCBM) are prepared and investigated. The morphology of films with 9, 25, 33, 50, 58 and 67% PCBM weight fraction is determined. The surface topography is probed with optical microscopy and atomic force microscopy whereas the lateral inner structures are...
Grazing incidence small angle X-ray scattering (GISAXS) and grazing incidence small angle neutron scattering (GISANS) have developed as advanced thin film characterization methods, which enables the detection of the three-dimensional (3D) film morphology. In particular thin block copolymer films have been successfully probed with GISAXS and GISANS. Accessing the 3D morphology and understanding the...
