Overview

 

Membrane technologies have been established in a wide range of industrial applications; the most successful processes are nowadays realized in very large scale. Organic polymers are the dominating materials, and intense research and development is focused on innovations leading to advanced membranes with higher separation performance adapted to specific requirements of important applications [1].

In  this  presentation  we  will  illustrate  by  recent  examples  from  own  research  how  the efficiency of membrane-based separations can be improved by developing membranes with higher intrinsic permeability at high selectivity and with high resistance to fouling as well as with added functionalities based on stimuli-responsive properties. The focus will be on the integration of functional inorganic and organic nanoparticles, tailored (block) copolymers or grafted polymeric nanolayers in polymer-based membranes as well as on additional, rather easy-to-implement processing or modification steps during membrane manufacturing or application, all leading to advanced or novel membranes for ultrafiltration, nanofiltration or osmotic processes [2-7]. Such generic innovations in membrane materials will contribute to more sustainable membrane processes for applications in water purification and water reuse, but potentially also in various other fields.
