Abstract
|
The aim of this work was to develop nanostructured polymer surfaces. For this purpose, diblock copolymers of poly(n-pentyl methacrylate) and poly(methyl methacrylate) with different block lengths and block length ratios were chosen, which show a bulk morphology with stacked lamellae or hexagonally packed cylinders. The bulk structure was characterized by SAXS investigations in dependence on temperature. Lamellar morphologies were found in a wide range of block length ratios. A set of polymers was selected for thin film investigations, and the phase behaviour of dip-coated films was studied by both AFM and GISAXS. In most cases, parallel ordered morphologies were formed, which is a result of the wetting behaviour of block copolymers. However, in a few cases, laterally ordered and demixed morphologies were detected, which are an essential precondition to obtain later on surfaces with regions of different wettability.
