Abstrakt

Within the area of polymer science, polystyrene-b-butadiene diblock copolymers have become object of intensive studies. We have participated in a GISAXS experiment in DESY, Hamburg, using thin film samples of the same polymer with different thickness and chemical treatment. In the attempt to understand the data, programs have been developed to simulate virtual experiments of both SAXS and GISAXS of lamellar diblock copolymer thin films. The programs are used for simulation and visualization of scattering by samples, such as those used in the experiment. Based on the scattering theory, the virtual experiments yield realistic data, which could provide relevant information for future experiments. An alternative for future work within virtual SAXS and GISAXS imaging of lamellar thin films is proposed.
