Study on Internal Structure Characterization of Nanoholes and Densely Branched Morphology Thin Films

The internal structures of thin films prepared from a long chain polystyrene-b-poly(ethylene oxide) (PS-b-PEO) diblock copolymer with nanoholes and densely branched morphologies were studied. The thickness of the lamellar mesophase repeat unit and the orientation of the PEO crystalline chain stems within the thin film were determined using grazing-incidence small- and wide-angle X-ray scattering (GISAXS…
