Polymer materials have been extensively utilized in diverse separation fields, especially in
membrane-based nanotechnologies for gas and liquid separations. The membrane …

Hundreds of polymers have been evaluated as membrane materials for gas separations, but
fewer than 10 have made it into current commercial applications, mainly due to the effects of …

Polyimides (PIs) are an important, well-established, and commercialized class of polymers
due to their extraordinary physical and chemical properties. They have been extensively …

Membrane processes have evolved as a competitive approach in CO2 separations
compared with absorption and adsorption processes, due to their inherent attributes such as …

Abstract Aliphatic/alicyclic (Al)-containing polyimides (PIs), including fully-Al-PIs and partially-
Al-PIs, are widely employed in electric, electronics, optical materials, and other advanced …

Penetrant-induced plasticization has prevented the industrial deployment of many polymers
for membrane-based gas separations. With the advent of microporous polymers, new …

This review provides a new perspective on the role of the state-of-the-art polymers of
intrinsic microporosity (PIMs) in key energy-intensive membrane-based gas separations …

Intrinsically ultramicroporous (< 7 Å) polymers represent a new paradigm in materials
development for membrane-based gas separation. In particular, they demonstrate that …

In this paper, the recent development of membrane-based carbon capture technologies is
reviewed, including membrane gas separation (MGS) and membrane contactor (MC). The …

Long-term physical aging and plasticization, two mobility-based phenomena that are
counterintuitive in the context of “rigid” polymers of intrinsic microporosity (PIMs), were …
