Morphology of an asymmetric ethyleneoxide–butadiene di-block copolymer in bulk and thin films
We present experiments on the melt and crystal morphology of a asymmetric semi-crystalline poly(ethylene/butylene- b-ethyleneoxide) diblock copolymer (PB h- b-PEO) in bulk as well as in thin films. Simultaneous small- and wide-angle X-ray scattering combined with AFM and TEM images reveal in the mel...

| description | We present experiments on the melt and crystal morphology of a asymmetric semi-crystalline poly(ethylene/butylene-
b-ethyleneoxide) diblock copolymer (PB
h-
b-PEO) in bulk as well as in thin films. Simultaneous small- and wide-angle X-ray scattering combined with AFM and TEM images reveal in the melt a bulk morphology of hexagonally packed cylinders of PEO in a PB
h matrix, that transforms into a hexagonal perforated lamellar phase upon crystallization. X-ray reflectivity of thin films of PB
h-
b-PEO in the melt indicates wetting layers at the top and bottom interfaces, which force the cylinders in the interior to orient parallel to the substrate. Crystallization of the PEO block leads to roughening of the air/film interface and causes lateral structuring coexisting with planar lamellar layers in thinner films. |
