“…Due to the direct contact with feed solution and draw solution, both active layer and substrate of FO membrane show significant influences on the FO performance. As fine-tuning the surface and separation properties of the two sides are equally important, this has multiplied the challenges in the fabrication of FO membrane compared to its pressure-driven counterparts [96]. Formation of double-skinned membrane is a feasibly way to render desired properties on both sides of the FO membrane.…”

Production of potable water or reclaimed water with higher quality are in demand to address water scarcity issues as well as to meet the expectation of stringent water quality standards. Forward osmosis (FO) provides a highly promising platform for energy-efficient membrane-based separation technology. This emerging technology has been recognized as a potential and cost-competitive alternative for many conventional wastewater treatment technologies. Motivated by its advantages over existing wastewater treatment technologies, the interest of applying FO technology for wastewater treatment has increased significantly in recent years. This article focuses on the recent developments and innovations in FO for wastewater treatment. An overview of the potential of FO in various wastewater treatment application will be first presented. The contemporary strategies used in membrane designs and fabrications as well as the efforts made to address membrane fouling are comprehensively reviewed. Finally, the challenges and future outlook of FO for wastewater treatment are highlighted.

Featured Application: Thin-film materials with degradability and recyclability for the fabrication of degradable, dissolvable, resorbable, and/or compatible electronic devices, especially transient resistive switching devices for security information storage and neuromorphic computing as well as environmental-friendly applications.Abstract: The environmental pollution generated by electronic waste (e-waste), waste-gas, and wastewater restricts the sustainable development of society. Environmental-friendly electronics made of degradable, resorbable, and compatible thin-film materials were utilized and explored, which was beneficial for e-waste dissolution and sustainable development. In this paper, we present a literature review about the development of various degradable and disposable thin-films for electronic applications. The corresponding preparation methods were simply reviewed and one of the most exciting and promising methods was discussed: Printing electronics technology. After a short introduction, detailed applications in the environment sensors and eco-friendly devices based on these degradable and compatible thin-films were mainly reviewed, finalizing with the main conclusions and promising perspectives. Furthermore, the future on these upcoming environmental-friendly electronic devices are proposed and prospected, especially on resistive switching devices, showing great potential applications in artificial intelligence (AI) and the Internet of Thing (IoT). These resistive switching devices combine the functions of storage and computations, which can complement the off-shelf computing based on the von Neumann architecture and advance the development of the AI.

“…The most common polymers that have been used for prepared asymmetric membrane are cellulose acetate, cellulose diacetate, triacetate, and their blend [60], while the typical TFC membranes are fabricated thin film of polyamide layer known as active layer on top of a microporous support layer of polysulfone (provide mechanical strength and stability) through interfacial polymerization process between trimesoyl chloride (TMC) and m-phenylenediamine (MPD) [61,62]. TFC polyamide membrane has attracted considerable attention in research and industrial areas compared with cellulose membranes due to its excellent performances in separation, high rejection of undesired compounds, high filtration rate, good mechanical strength and flexibility to select and optimize material to form a microporous substrate and a thin selective layer of film [61][62][63][64].…”

For decades, the water deficit has been a severe global issue. A reliable supply of water is needed to ensure sustainable economic development in population growth, industrialization and urbanization. To solve this major challenge, membrane-based water treatment technology has attracted a great deal of attention to produce clean drinking water from groundwater, seawater and brackish water. The emergence of nanotechnology in membrane science has opened new frontiers in the development of advanced polymeric membranes to enhance filtration performance. Nevertheless, some obstacles such as fouling and trade-off of membrane selectivity and permeability of water have hindered the development of traditional polymeric membranes for real applications. To overcome these issues, the modification of membranes has been pursued. The use of macromolecules for membrane modification has attracted wide interests in recent years owing to their interesting chemical and structural properties. Membranes modified with macromolecules have exhibited improved anti-fouling properties due to the alteration of their physiochemical properties in terms of the membrane morphology, porosity, surface charge, wettability, and durability. This review provides a comprehensive review of the progress made in the development of macromolecule modified polymeric membranes. The role of macromolecules in polymeric membranes and the advancement of these membrane materials for water solution are presented. The challenges and future directions for this subject are highlighted.
