“…The brush‐like structure of macromolecules can create pathways or channels that facilitate diffusion of species through membrane. This promotes increased permeability, which, in turn, leads to faster and more efficient separation processes 20,21 . Molecular brushes can be designed with specific functional groups that selectively interact with certain components of a liquid mixture, thereby significantly improving membrane selectivity.…”

“…This promotes increased permeability, which, in turn, leads to faster and more efficient separation processes. 20,21 Molecular brushes can be designed with specific functional groups that selectively interact with certain components of a liquid mixture, thereby significantly improving membrane selectivity. The presence of several independently variable architectural parameters of molecular brushes, including the length of side chains and the grafting density, makes it possible to control characteristics of the resulting membrane material at the molecular level.…”

Macromolecules of complex architecture find application as modifiers of commercial polymeric membrane materials. In this work, copolyimide molecular brushes (coPI) composed of polyimide backbone and poly(methacrylic acid) side chains were used to modify poly(m‐phenylene iso‐phthalamide) (PPA). Structure, physical, mechanical, and transport properties of dense nonporous PPA/coPI membranes containing up to 10 wt% coPI were studied. The effect of included coPI on the membrane structure was estimated using atomic force microscopy and mechanical tests. The coPI modifier contributes to the additional formation of free volume elements evenly distributed throughout the membrane. Transport properties of PPA/coPI membranes were investigated via sorption tests and pervaporation separation of methanol (MeOH) and methyl tert‐butyl ether (MTBE) mixtures. The inclusion of coPI modifier in the PPA membrane leads to an increase in the total flux of the membrane. The highest separation factor was found for the PPA/coPI membrane containing 10 wt% coPI; transport properties of the best membrane were compared with the literature data on separation of the azeotropic MeOH–MTBE mixture.

“…71 SBS copolymers were also used as soft polymeric backbones in graft copolymers for MMMs with ZIF-8 alone 83 or combined with [EMIm][TFSI] ionic liquid. 84 The rubbery and CO 2 -philic characters of the SBS polymer backbone further improved the dispersion of the ZIF-8 filler 86 The advanced synthesis strategy allowed good control of the number and length of the PEDEGA soft grafts. The new grafted copolymer architecture prevented POE crystallization, even for very high POE contents, and led to a specific nanostructuration of the graft copolymers, inducing their high performance for CO 2 capture.…”

The urgency of curbing global warming triggered by growing CO 2 emissions has generated significant attention. Direct air capture (DAC) is a crucial and feasible technology to cut CO 2 emissions at nonpoint sources, therefore achieving negative emissions. Solid porous sorbents have drawn increasing attention for CO 2 capture from the atmosphere with ultralow CO 2 concentration (ca. 400 ppm). However, most related studies focus on nanoparticle-based adsorbents and their functionalized counterparts, which are more prone to lose weight in the atmosphere. In this context, we summarize nanoparticle composite adsorbents, including zero-dimensional powders, one-dimensional fibers, two-dimensional membranes, and three-dimensional aerogels, and assess the physicochemical properties and typical applications of major types of nanoporous adsorbents in the field of CO 2 adsorption and separation with emphasis on DAC. The multidimensions of emerging adsorbents versus CO 2 uptake are discussed and compared separately. Combined with recent reported advances, we provide deep insights for the design and synthesis of multifunctional materials for efficient CO 2 adsorption. Moreover, life cycle and technoeconomic assessments of DAC using different materials are briefly estimated. Finally, challenges and current trends in the DAC system for commercialization have been put forward.
