A simple approach was developed to computationally construct a polymer dataset by combining simplified molecular-input line-entry system (SMILES) strings of a targeted polymer backbone and a variety of molecular fragments. This method was used to create 14 polymer datasets by combining seven polymer backbones and molecules from two large molecular datasets (MOSES and QM9). Polymer backbones that were studied include four polydimethylsiloxane (PDMS) based backbones, poly(ethylene oxide) (PEO), poly(allyl glycidyl ether) (PAGE), and polyphosphazene (PPZ). The generated polymer datasets can be used for various cheminformatics tasks, including high-throughput screening for gas permeability and selectivity. This study utilized machine learning (ML) models to screen the polymers for CO 2 /CH 4 and CO 2 /N 2 gas separation using membranes. Several polymers of interest were identified. The results highlight that employing an ML model fitted to polymer selectivities leads to higher accuracy in predicting polymer selectivity compared to using the ratio of predicted permeabilities.

“…PU is a polymer with exceptional properties such as biodegradability, biocompatibility, and unique chemistry that make it a vital component in polymeric membranes. [ 119 ] However, membrane fouling is a common and severe challenge in membrane separation processes, which can reduce membrane flux and affect effluent quality. To achieve sustainable membrane operation, it is necessary to prevent or mitigate membrane fouling.…”

Recent advancements in bioengineering and medical devices have been greatly influenced and dominated by synthetic polymers, particularly polyurethanes (PUs). PUs offer customizable mechanical properties and long‐term stability, but their inherent hydrophobic nature poses challenges in practically biological application processes, such as interface high friction, strong protein adsorption, and thrombosis. To address these issues, surface modifications of PUs for generating functionally hydrophilic layers have received widespread attention, but the durability of generated surface functionality is poor due to irreversible mechanical wear or biodegradation. As a result, numerous researchers have investigated bulk modification techniques to incorporate zwitterionic polymers or groups onto the main or side chains of PUs, thereby improving their hydrophilicity and biocompatibility. This comprehensive review presents an extensive overview of notable zwitterionic PUs (ZPUs), including those based on phosphorylcholine, sulfobetaine, and carboxybetaine. The review explores their wide range of biomedical applications, from blood‐contacting devices to antibacterial coatings, fouling‐resistant marine coatings, separation membranes, lubricated surfaces, and shape memory and self‐healing materials. Lastly, the review summarizes the challenges and future prospects of ZPUs in biological applications.

“…14,15 The PU-based membranes for GS applications have some advantages, like structural versatility, high permeability, and good film ability. 16 However, the selectivity of the PU membranes is limited, which has led to the development of the PU blend membranes with other polymers such as polyethylene glycol (PEG), poly(amide imide) (PAI), poly(vinyl acetate) (PVAc), poly(methyl methacrylate) (PMMA), poly(vinyl alcohol) (PVA), PSf, PES, PI, and PEI. 9 Blending PU with another polymer significantly improves gas selectivity compared with neat PU membranes.…”

“…Polymer blending is a modification technique that combines the benefits of a highly permeable and selective polymer in a time-efficient and cost-effective manner. , By simply managing the gas transport properties of the polymers, a polymer blend creates a new material with distinct physical characteristics. A polymer blend can be categorized into three types based on its phase behavior: miscible, immiscible, and partially miscible; these blend types, except immiscible polymer blends, have been employed in the preparation of the GS membranes. , The PU-based membranes for GS applications have some advantages, like structural versatility, high permeability, and good film ability . However, the selectivity of the PU membranes is limited, which has led to the development of the PU blend membranes with other polymers such as polyethylene glycol (PEG), poly(amide imide) (PAI), poly(vinyl acetate) (PVAc), poly(methyl methacrylate) (PMMA), poly(vinyl alcohol) (PVA), PSf, PES, PI, and PEI .…”

In this research, gas separation blend membranes composed of polyurethane (PU) and polycarbonate (PC) were developed, and the influence of incorporating PC into the PU matrix on the microstructure and separation performance was investigated. The PU polymer was synthesized using a two-step polymerization approach. The blend membranes were thoroughly characterized using SEM, DSC, XRD, AFM, and FTIR analyses. The compatibility of the PU/PC blend was theoretically analyzed using surface energy and Gibbs free energy methods. The results showed that the PU/PC blends are partially compatible. Accordingly, the maximum achievable PC loading in the PU matrix was 25 wt %. Analysis of the SEM results revealed that the blend membrane containing 25 wt % PC demonstrated decreased levels of PU/PC interaction compared to the membranes with PC contents below 25 wt %. Incorporating PC into the PU matrix led to a decreased chain mobility, increased membrane crystallinity, and the development of a rough microstructure. The CO 2 /N 2 selectivity of the neat PU and PC membranes was measured to be 32.5 and 120, respectively. However, the blending of 10 wt % PC increased the CO 2 /N 2 selectivity to 41.2. Notably, the PU95/PC5 blend membrane demonstrated the highest selectivity (11.85) for the CO 2 /CH 4 separation. Moreover, increasing the upstream pressure enhanced the permeabilities of the CO 2 , CH 4 , and N 2 through all membranes.
