Polymers with high free volume

In the “polymers with high free volume” research area, monomers and polymers are being developed specifically for particular membrane applications. Here the necessary polymer characteristics are defined by the intended application, e.g. solvent-resistant basic polymers for integral asymmetrical membranes, membranes with catalytic properties or polymers with extremely high free volume for gas separation or pervaporation.

PIM-Membrane PIM-Membrane

Vitreous polymers with high free volume can be used in a number of different membrane applications (nanofiltration, pervaporation, vapour and gas separation). This novel class of polymer – also referred to as polymers of intrinsic microporosity (PIM) – was developed at the University of Manchester; evidence of its extraordinarily high gas permeability was first established by the Helmholtz-Zentrum Geesthacht Research Centre. In cooperation with the University of Manchester, the separation properties and the long-term stability of the PIMs are further optimised.

In order to comprehensively characterise the property profile of this novel material class, all of the institute's available analytical techniques are used in a targeted way.
