Kurzfassung englisch:
Well defined amphiphilic block copolymers containing a polydimethyl siloxane (PDMS) and a poly(ethylene oxide) block (PEO) were synthesized by ring opening polymerization of hexamethylcyclotrisiloxane, followed by chain extension with a PEO block of a defined length. These amphiphilic molecules were used as templates in a solvent-evaporation driven synthesis approach to self-assembled mesostructured silica films. Thin films and powders were prepared, and the resulting material was characterized by X-ray diffraction, transmission electron microscopy, and 29Si} and 13C solid state NMR. The behavior of the PEO-b-PDMS block copolymer during heat treatment up to 600°C was followed in detail by solid state NMR.
