“…It is well-known that the solvent used for film casting can influence the permeability behavior strongly. 24 More drastic changes were observed in the case of hydrolyzed PIM1-3H and PIM1-5H, which were solution cast from DMF. The overall CO 2 uptake was smaller than for the precipitated samples, but more importantly, a large hysteresis upon desorption was observed for those two samples.…”

“…Values for the apparent BET surface area of PIMs are given in [44,55,103]. Only a few PIMs match or demonstrate higher apparent surface area than PIM-1, and these are prepared from monomers containing highly rigid aromatic substituents such as A8, A18, and B16 [76,80,85].…”

This paper focuses on polymers that demonstrate microporosity without possessing a network of covalent bonds-the so-called polymers of intrinsic microporosity (PIM). PIMs combine solution processability and microporosity with structural diversity and have proven utility for making membranes and sensors. After a historical account of the development of PIMs, their synthesis is described along with a comprehensive review of the PIMs that have been prepared to date. The important methods of characterising intrinsic microporosity, such as gas absorption, are outlined and structure-property relationships explained. Finally, the applications of PIMs as sensors and membranes for gas and vapour separations, organic nanofiltration, and pervaporation are described.

“…Accordingly, the gas transport properties of PIM-1 are considerably influenced by various film formation and treatment protocols including casting solvent type and drying conditions [22]. Table 3 presents the gas permeabilities and selectivities of PIM-1 membranes, which were prepared by various solvents (e.g., tetrahydrofuran (THF), dichloromethane (DCM), and chloroform) and treated by immersion in water or methanol.…”

“…Among these novel materials, PIM-1, containing the contorted spirobisindane unit, has attracted the most attention due to its relative ease of synthesizing high molecular weight polymer and the combination of outstanding permeability with moderate selectivity, especially for O 2 /N 2 and CO 2 /CH 4 pairs, which overcome the upper bound trade-off proposed by Robeson [18,19]. Since the initial reports of Budd et al and McKeown et al, structurally new PIMs and additional data on PIM-1 have appeared [20][21][22][23][24][25].…”

Gas transport behavior of mixed-matrix membranes composed of silica nanoparticles in a polymer of intrinsic microporosity (PIM-1) Ahn, Juhyeon; Chung, Wook-Jin; Pinnau, Ingo; Song, Jingshe; Du, Naiying; Robertson, Gilles P.; Guiver, Michael D.This article appeared in a journal published by Elsevier. The attached copy is furnished to the author for internal non-commercial research and education use, including for instruction at the authors institution and sharing with colleagues. Recently, high-free volume, glassy ladder-type polymers, referred to as polymers of intrinsic microporosity (PIM), have been developed and their reported gas transport performance exceeded the Robeson upper bound trade-off for O 2 /N 2 and CO 2 /CH 4 . The present work reports the gas transport behavior of PIM-1/silica nanocomposite membranes. The changes in free volume, as well as the presence and volume of the void cavities, were investigated by analyzing the density, thermal stability, and nano-structural morphology. The enhancement in gas permeability (e.g., He, H 2 ,O 2 ,N 2 , and CO 2 ) with increasing filler content shows that the trend is related to the true silica volume and void volume fraction. Crown
