“…On the other hand, the peak of C-O-C stretching was around 1095 cm À1 as well, that formed by PVA during membrane preparation. 43 The characteristic infrared absorption peaks of imide structure above do not exhibit in the ATR-FTIR spectrum of blending membrane M-2 without imidization. Distinct peaks representative of the amide group before imidization are clearly visible, referring to Figure 2, the characteristic peaks at 1658 cm À1 and 1557 cm À1 are attributed to C¼O stretch and C-N stretch of the amide group, respectively.…”

Fluorinated polyimide and PVA blending membranes were prepared by aqueous solution casting. We chose a poly (amic acid) ammonium salt (PAAS) in aqueous solution based on a novel green strategy as the PI precursor. The blending membranes were characterized by ATR-FTIR, DSC, TGA and gas permeation measurement. The ATR-FTIR analysis revealed that the imidization reaction of 6FPI based on aqueous precursor was completed at 180°C and hydrogen bonds formed between PVA and 6FPI. 6FPI showed good compatibility with PVA segment in blending membranes without obvious separated phase structure. The blending membranes showed high separation properties, for blending with 6FPI the gas separation performance stability was improved due to the hydrogen bonds between hydroxyl groups of PVA and carbonyl groups of 6FPI, and the rigid structure of 6FPI. At high operating pressure 10 bar, the CO2 permeability and CO2/N2 selectivity remained rather high. Using water as the solvent in the PAAS synthesis and membrane preparation is more environmentally friendly and less costly.

“…Hybrid membrane, or mixed matrix membrane (MMM), which normally consists of an inorganic component such as zeolites, carbon nanotubes, silicates, alumina, or MOFs incorporated into the polymer matrix in the nanoparticles form (Vinoba et al, 2017;Ahmad et al, 2018;Sarfraz and Ba-Shammakh, 2018;Dilshad et al, 2019;Julian et al, 2019), is becoming a new trend to improve polymeric membranes' properties, as it could possess both advantages of inorganic and organic materials. Incorporating inorganic particles improves both the mechanical and thermal properties, making the polymeric membranes more stable.…”

Carbon Capture From Flue Gas and the Atmosphere: A Perspective

2020

Climate change has become a worldwide concern with the rapid rise of the atmospheric Co2 concentration. To mitigate Co2 emissions, the research and development efforts in Co2 capture and separation both from the stationary sources with high Co2 concentrations (e.g., coal-fired power plant flue gas) and directly from the atmosphere have grown significantly. Much progress has been achieved, especially within the last twenty years. In this perspective, we first briefly review the current status of carbon capture technologies including absorption, adsorption, membrane, biological capture, and cryogenic separation, and compare their advantages and disadvantages. Then, we focus mainly on the recent advances in the absorption, adsorption, and membrane technologies. Even though numerous optimizations in materials and processes have been pursued, implementing a single separation process is still quite energy-intensive or costly. To address the challenges, we provide our perspectives on future directions of Co2 capture research and development, that is, the combination of flue gas recycling and hybrid capture system, and one-step integrated Co2 capture and conversion system, as they have the potential to overcome the technical bottlenecks of single capture technologies, offering significant improvement in energy efficiency and cost-effectiveness.

“…This technology combines the membrane separation capability with adsorption activities of adsorbents for gas/liquid molecules separation and thus, it is considered as a most efficient technique compared to solo adsorption (7). Further benefits of membrane systems are smaller footprints and easy to scale-up making this technology an appropriate candidate for industrial applications (11)(12)(13)(14)(15)(16)(17).…”

In the past few years, research on the fabrication of deep eutectic solvents (DESs)-based supported liquid membranes (SLMs) is increasing tremendously due to their significant advantages such as low mass transport resistance, high performance, easy scale-up, low cost and simple operation. However, fabrication of DES-based SLMs is challenging and highly dependent on the fabrication parameters: DES properties and properties of membrane supports. Subsequently, the fabrication methods, immersion, pressurebased impregnation and vacuum filtration also affect the permeation performance of DES-based SLMs in liquids and gases separation. Furthermore, the SLM durability is influenced by the DES properties and process parameters including: temperature, pressure, and feed composition. Firstly, present work reviews the current progress and fabrication of DES-based SLMs. Subsequently, it presents a perspective on different strategies that use DESs as a unique tunable platform to design advanced SLMs for liquids and gases separation reported in the literature. In the next step, performances of the SLMs membranes for liquids and gases separation are described in details. The effects of process parameters on DES-based SLMs are also highlighted prior to the challenges. Lastly, challenges and future research opportunities are highlighted.
