Abstract
The shortage of water resources has been one of the most worrying world crises. Thus, one promising way to address the need for water is desalination. In recent years, forward osmosis has been an emerging technique in water treatment applications, especially desalination. This is due to the enhanced quality of water production, which resulted from reduced fouling propensity and high salt rejection. However, the selection of an ideal draw agent for the forward osmosis desalination process is still a challenging issue. Draw agents for forward osmosis desalination should be distinguished with their high osmotic pressure, low reverse solute flux, and facile regeneration. Lately, hydrogels have offered some advantages, such as negligible reverse solute flux and their capability to capture large amounts of water. These merits made different types of hydrogels, like thermoresponsive, electroresponsive, magnetic responsive, gas-responsive, multi-responsive, green, and other hydrogels’ classes, be recognized as draw agents for forward osmosis desalination. In this review, we will describe how hydrogels could be applied as drawing agents for the forward osmosis desalination approach and their operational advantages and drawbacks. In addition, we will display and discuss the recent research output that aimed to improve the performance of hydrogels as draw agents for the forward osmosis desalination.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
