WebDec 1, 2024 · Polymers of intrinsic microporosity (PIMs) are a series of polymers with rigid and contorted chain structures and continuous microporous structures (<2 nm) [ 19]. Moreover, their structures are suitable NF separation size. For example, PIM-1 is widely used for gas separation and exhibits excellent permeation and selectivity. Polymers of intrinsic microporosity (PIMs) are a unique class of microporous material developed by research efforts led by Neil McKeown, Peter Budd, et al. PIMs contain a continuous network of interconnected intermolecular voids less than 2 nm in width. Classified as a porous organic polymer, PIMs generate … See more PIMs require that the non-network macromolecular structure is rigid and non-linear. In order to maintain permanent microporosity the rotation along the polymer chain must be prohibited through the use of fused ring … See more Due to the presence of intrinsic microporosity these polymers have high-free volume, high internal surface area, and have a high affinity for gases. A novel property of PIMs is … See more fixing loose charging usb input
