Analysis of the transport of the individual gas mixture components in polymers of intrinsic microporosity and
PIM-based mixed matrix membranes
Due to the increasing need for sustainability in all industrial sectors, membrane operations are gaining territory over energy
demanding and less environmentally friendly traditional separation processes. Successful implementation of membrane
technology requires the development of novel materials with enhanced performance. In the field of gas separation, polymers of
intrinsic microporosity (PIMs) and mixed matrix membranes (MMMs) are two classes of such materials which are intensively
investigated by the scientific community. PIMs have exceptional permeation properties owing to their stiff contorted polymer
backbone that induces an unusually high fractional free volume, in combination with a modest size-sieving behavior. MMMs
consist of porous materials dispersed in a dense polymer matrix and metal organic frameworks (MOFs) are often used as
such fillers because of their generally good compatibility with the polymer and their specific pore structure. MOFs may
further increase the selectivity of polymeric membranes, enhancing the permeability of certain gas species and blocking
others, especially MOFs with a high aspect ratio. The use of novel materials also requires better characterization methods to
analyze their performance. In this light, the present paper discusses the development of a novel method for the analysis of
the individual permeability and diffusion coefficients of gas mixtures in polymeric membranes, using in-line analysis of the
permeate composition by a Quadrupole Mass Spectrometer. A comparison is made with the so-called time lag method for pure
gases and some peculiarities of the gas and vapor transport in PIMs and other high free volume polymers will be discussed.
