In the field of separation processes, immobilized functional polymers, block copolymer or inverse opal structures attracted enormous attention as potential filtration membranes.

In our group we investigate the usability of tailor-made polymer architectures based on block copolymers or core/shell particles for the preparation of hierarchically structured porous materials featuring various functional groups.

One concept focusses on the self-assembly and phase inversion of amphiphilic polymers while the other concept is based on the melt-shear organization technique followed by core particle removal.

These porous free-standing hybrid or polymer-based film materials are potential candidates for smart switchable membranes, optical sensors and catalyst supports.
