Book Description :

To decrease the current level of CO2 emissions appreciably, more efficient CO2-capture technologies are needed. Absorption is currently used widely to lower CO2 level in gases. However, it is relatively expensive (in terms of both operating and capital costs), bulky, and challenging to operate (foaming, entrainment and flooding of the absorber). Compared to absorption, the membrane technology is more energy-efficient, has lower operating costs, is compact and modular, and has a simple process. Among membranes, polymer of intrinsic microporosity (PIM) membranes with high free-volume created by rigid moieties have superior gas-transport properties. However, presently these membranes suffer from two fundamental and industrially0́0important problems of low-to-modest selectivity and fast physical aging. Among PIMs, pentiptycene-based membranes exhibit satisfactory selectivity, and excellent resistance against plasticization and physical aging. However, the presence of two ethereal oxygens in the backbone of these membranes causes efficient chain packing, resulting in a decrease in free volume and consequently gas permeability. Pentiptycene is a highly rigid moiety from iptycene family consisting of five benzene rings forming an H-shaped core block. A fractional free volume (FFV) of less than 0.2 has been reported for existing pentiptycene-based membranes. To enhance the FFV of pentiptycene-based membranes, in this work: for the first time a pentiptycene-based dianhydride containing two etheric oxygens was synthesized and characterized; and a high molecular-weight pentiptycene-based polyimide was synthesized and characterized. The polyimide showed remarkable thermal stability, excellent solubility in common organic solvents, and the highest CO2 permeability (812 barrer) among all reported pentiptycene-containing polymers (about 6 times higher than the most permeable one) without sacrificing the selectivity. Currently polymer membranes suffer from the trade-off relationship between the permeability and selectivity. The fabrication of membranes made from polymers embedded with nanomaterials can lead to mixed matrix membranes (MMMs) with high gas permeability and excellent sieving ability. However, the agglomeration of nanomaterials, the formation of interfacial defects, and the incompatibility between the polymer and nanomaterials are still challenges in the fabrication of MMMs. In this research, these fundamental problems were studied through engineering the dispersion of the nanoparticles in polymer matrices via nanoparticles functionalization and considering polymer chemistry. TiO2 nanoparticles were grafted using 3-aminopropyl-diethoxymethylsilane [a silane coupling agent (AS)], their surface was then modified using carboxymethyl chitosan (CMC), and, the modified TiO2 nanoparticles were incorporated into the Pebax as the polymer matrix. The Pebax-modified-TiO2 nanocomposite membranes showed improved CO2 permeability and CO2/N2 selectivity, compared to the pristine Pebax. Characterization techniques showed good compatibility of the nanoparticles and the polymer and satisfactory dispersion of the nanofillers into the polymer. The influence of cyanuric chloride (CC) nanoparticles and its derivatives, melamine (M) and 2, 4, 6-trihydazino-1, 3, 5-triazine (THDT), on the performance and characteristics of a polyurethane (PU)-based nanocomposite membranes was investigated. Characterization results showed that the CC nanoparticles were mostly distributed in the PU hard segments. Also, M and THDT nanoparticles were scattered in the PU soft segments. Incorporating organic nanoparticles with many amine groups (i.e., M and THDT) showed to be an appealing strategy to fabricate highly selective membranes. This work indicated how robust interfacial interactions between nanoparticles and a polymer improve the polymer/nanoparticles compatibility and lower the level of defects in CO2-separating membranes. Increasing daily demand for clean water and limited fresh water resources has motivated studies on sustainable water furification. The membrane technology is suitable for water and wastewater treatment owning to its compactness, simplicity, small footprints, and sustainability. Among membrane-based processes, forward osmosis (FO) is one of the most promising methods having high water recovery, hydraulic pressure independency, and low-cost. However, fouling and biofouling of thin-film composite (TFC) FO membranes are still major challenges. An attractive strategy to improve fouling-resistance of FO membranes is the addition of antibacterial nanomaterials to the active layer of a TFC membrane. We studied the primary antibacterial mode-of-action (MoA) of Ti3C2Tx MXene nanosheets against both Gram-negative and Gram-positive bacteria. To characterize the antibacterial properties of Ti3C2Tx MXene in a well-quantitative manner, we used the flow cytometry (FC) and fluorescence imaging (FI) techniques. Our results indicated that the antibacterial activity of the MXene nanosheets are both size- and time-dependent; that is, smaller sizes of the nanosheets result in the release of bacteria cytoplasmic DNA and eventually dispersion of the bacteria envelope. In another work, we synthesized and characterized a silver-based metal-organic framework (Ag-MOF) embellished with graphene oxide (GO) [GO-Ag-MOF] with potent antibacterial activity. A thin-film nanocomposite (TFN) membrane with superior anti-biofouling and good antifouling properties was fabricated the GO-Ag-MOF nanocomposite to the selective layer of a TFC membrane. In addition to membrane characterization, fouling and antifouling resistance of the membrane was assessed through FO experiments in the presence of sodium alginate and E.coli and in the feed solution, respectively.

Book Description :

There is a growing need for better membranes in several emerging application fields especially those related to energy conversion and storage as well as to water treatment and recycling. Processability, is an important functional property, often ignored, especially in the early discovery phase for new materials, but it should be one of the most important properties, that needs to be considered in the development of better membrane materials. Useful membrane materials have to be capable of being formed into thin membranes, in particular for membrane gas separation, water treatment and desalination, and then packaged, into large area membrane modules. All gas separation membranes that are in current commercial use are based on polymers, which are solution-processable. This book intends to deal with composite, in most cases hybrid polymer-based membranes for three separate application fields: energy conversion, energy storage and water treatment and recovery. Each chapter will explain clearly the various membrane processes then go on to discuss in detail the corresponding advanced membranes used. The logic that lies behind this is that you have to understand the process in order to develop new high-performance membranes. By taking this approach, the author aims to overcome the disconnection that currently exists between membrane materials scientists and industrial process engineers. Discusses interdisciplinary content by a single author, approaching synthesis and development of materials from the perspective of their processability Describes the novel aspects of membrane science that is related to energy storage, conversion and wastewater treatment Presents an emphasis on scientific results which have an impact on real applications in terms of renewable and clean energy challenges
