| The lecture will cover the morphological properties of block copolymers with well controlled design and composition (host) blended with (mostly) low molecular weight compounds (guest). The influence of the guest molecules' nature and the blending ratio on the microphase separated structures in thin films before and after removal of the guest molecules will be highlighted. In addition, so-called integral asymmetric membranes based on these block copolymers have been prepared by non-solvent induced phase separation. Their properties will be discussed. Host polymers are prepared via living anionic polymerization. The blends are obtained by casting from common solution. Morphological characterizations are carried out by electron microscopy and atomic force microscopy. |
