The ma- terial therefore has all the advantages of a synthetically pro- ducible polymer. The material’s crosslinked structure makes it resistant to organic solvents. Furthermore, the freedom of choice of chemical components enables targeted setting of the desired properties, such as e.g. hydrophilic properties or elasticity. Now that the production of easily modiﬁed polymer foams with ideal porosity in a single-stage synthesis has been shown, the macroporous material should continue to be developed so that it can be applied for colonization with microbial cells for material enrichment. 1 Manufactured functional polymer foam. 2 Scanning electron microscope image of the manufactured foam. 3 Single-stage synthesis of the foam using an emulsion polymerization process. Funding We would like to thank the Fraunhofer-Gesellschaft for funding the project “Bakterien hinter Gittern zur Rückgewinnung von Phosphor” within the Fraunhofer “Netzwert” symposium 2011.
