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 …

Since the first report of the synthesis of poly [1-(trimethylsilyl)-1-propyne][poly (TMSP)] in
1983, a large number of publications, presently up to about 350 journal articles and patents …

Separating CH 4/N 2 mixture is challenging, and performance of the existing materials is still
open to improvement. In this study, we examined both the adsorption-and membrane-based …

The promise of ultrapermeable polymers, such as poly (trimethylsilylpropyne)(PTMSP), for
reducing the size and increasing the efficiency of membranes for gas separations remains …

This short Perspective conveys to the general reader of Macromolecules basic approaches
of materials science of polymeric membranes for gas and vapor separation. The relations …

The empirical upper bound relationship for membrane separation of gases initially
published in 1991 has been reviewed with the myriad of data now presently available. The …

A detailed study of gas permeation, thermodynamic properties and free volume was
performed for a novel polymer of intrinsic microporosity (PIM-1). Gas permeability was …

Transport in non-porous polymeric membranes is based on the so-called 'solution–
diffusion'concept [1, 2]. This model, formulated in the 19th century, is grounded in the works …

With the growing concern about global warming placing greater demands on improving
energy efficiency and reducing CO2 emissions, the need for improving the energy intensive …

In contrast to the performance of traditional filled polymer systems, penetrant permeability
coefficients in high-free-volume, glassy poly (4-methyl-2-pentyne)(PMP) increase …
