Scattering patterns of block-copolymer PI550-b-PFS50 in decane solutions. The molecules have self-assembled into rigid cylinders, which are oriented by applying a weak electric field. The combination of (a) the SAXS pattern and (b) the WAXS pattern is required to elucidate the internal structure of the cylinders in both (c) the longitudinal direction and (d) the transverse direction, as well as the dimensions of the cylinders and their degree of orientation.
