Ladder polymers of intrinsic microporosity from superacid-catalyzed Friedel-Crafts polymerization for membrane gas separ...
Polymers of intrinsic microporosity have attracted comprehensive attention in membrane-mediated gas separation because of their rigid and contorted structure that facilitates well-defined microporosity for fast and selective gas transport. We report a new macromolecular design synthesizes semi-ladder and fully-ladder polymers of intrinsic microporo...

Highly Selective Benzimidazole-Based Polyimide/Ionic Polyimide Membranes for Pure- and Mixed-Gas CO2/CH4 Separation
This paper reports two new series of benzimidazole functionalized polyimides and ionic polyimides for highly selective membranes with great potential for natural gas sweetening. It has been demonstrated that both the -NH groups in the benzimidazole moieties and the corresponding ionic groups after N-quaternization tighten the microporous structure ...

A ground breaking polymer blend for CO2/N2 separation
© 2018 Elsevier Ltd. All rights reserved. The commercial polyetherimide sulfone polymer Extem was blended with polyethersulfone (PES) to achieve a new, highly selective membrane for CO2/N2 separation in order to allow for a breakthrough in carbon capture applications. The miscibility and molecular interaction between PES and Extem for blend composi...

Temperature influence and CO2 transport in foaming processes of poly(methyl methacrylate)-block copolymer nanocellular a...
Fabricated by high-pressure or supercritical CO2 gas dissolution foaming process, nanocellular and microcellular polymer foams based on poly(methyl methacrylate) (PMMA homopolymer) present a controlled nucleation mechanism by the addition of a methylmethacrylate-butylacrylate-methylmethacrylate block copolymer (MAM), leading to defined nanocellular...
