X-ray reflectometry (XR) was carried out on amphiphilic diblock copolymer poly(α-methylstyrene)-block-poly(decyl 4-vinylpyridine) monolayers on a water surface and on a glass plate. From XR data, the layer thickness and surface and interface roughness were determined. For comparison, atomic force mi...
