抄録

Microphase-separated structures of a Poly(deuterated styrene-block-2- vinylpyridine) (dPS-b-PVP) thin films were studied by transmission electron microtomography (TEMT) and neutron reflectivity (NR). Note that the dPS-b-P2VP shows cylindrical morphology in a bulk state. The thin film was prepared by spin-coating on a Si substrate, and then annealed at 170°C for 14 days before TEMT and NR experiments. Three-dimensional (3D) volume data was obtained by TEMT. The concentration profile of dPS in direction perpendicular to the substrate, i.e. depth profiles, was independently obtained from 3D volume data and NR. In addition, the concentration profile obtained by TEMT was used as an initial guess in a model fitting of reflectivity profile. We examine the validity of such model fitting in the reflectivity measurements.
