Nanomaterials have been extensively used in polymer nanocomposite membranes due to the inclusion of unique features that enhance water and wastewater treatment performance. Compared to the pristine membranes, the incorporation of nanomodifiers not only improves membrane performance (water permeability, salt rejection, contaminant removal, selectivity), but also the intrinsic properties (hydrophilicity, porosity, antifouling properties, antimicrobial properties, mechanical, thermal, and chemical stability) of these membranes. This review focuses on applications of different types of nanomaterials: zero-dimensional (metal/metal oxide nanoparticles), one-dimensional (carbon nanotubes), two-dimensional (graphene and associated structures), and three-dimensional (zeolites and associated frameworks) nanomaterials combined with polymers towards novel polymeric nanocomposites for water and wastewater treatment applications. This review will show that combinations of nanomaterials and polymers impart enhanced features into the pristine membrane; however, the underlying issues associated with the modification processes and environmental impact of these membranes are less obvious. This review also highlights the utility of computational methods toward understanding the structural and functional properties of the membranes. Here, we highlight the fabrication methods, advantages, challenges, environmental impact, and future scope of these advanced polymeric nanocomposite membrane based systems for water and wastewater treatment applications.

“…In order to alleviate the severe water scarcity problems, 4,5 a variety of methods have been developed to obtain fresh water from sewage and seawater. [6][7][8] Among them, solar-driven steam generation via interfacial heating has received increasing attention owing to the abundance of solar energy and negligible environmental impact. [9][10][11] During the past years, various interfacial evaporators with rationally designed photothermal materials have been developed.…”

“…Naturally occurring molecules often offer us opportunities to fabricate functional materials with desirable properties. − Gallic acid (GA) is a typical kind of naturally occurring polyphenolic compound available from many fruits and vegetables. , GA can coordinate with Fe(III) in an aqueous solution through its pyrogallol and carboxylic groups, resulting in ink-like products with a broad range of light absorption. − Besides, GA and Fe(III) are both harmless and commonly found in plants and animals as micronutrients. The GA@Fe(III) network can not only form stable versatile adhesive coatings but also be able to degrade quickly in acidic conditions without generating harmful degradation products. − Moreover, hydrophilic poly(vinylidene fluoride) (PVDF) is selected as a substrate because of its high porosity, outstanding mechanical properties, and chemical stability .…”

Solar steam generation is a robust and environmentally friendly way to obtain fresh water and alleviate the water shortage problem. Although a wide variety of steam generation devices have been well documented, most fabricated materials are often only suitable for one device and generally difficult to be removed, resulting in a disposable device. This may raise serious concerns about the total cost issues, particularly for those devices with complex and well-tailored microstructures. Thus, it is urgent to develop a robust and dynamic photothermal coating that can be easily removed and flexibly switched between different installations with stable photothermal conversion ability. In this work, we report a degradable and recyclable metal-phenolic network-based photothermal coating assembled from two kinds of naturally occurring building blocks [gallic acid (GA) and Fe(III)]. Hydrophilic poly(vinylidene fluoride) (PVDF) was selected as the substrate, resulting in the robust GA@Fe(III)@PVDF membrane, which can achieve a high evaporation rate of 1.539 kg m −2 h −1 and a superb steam generation efficiency of 90.2% under 1 sun illumination. Impressively, the GA@Fe(III) coating can be degraded under acidic condition rapidly, and the recovered PVDF can be recoated by the GA@Fe(III) networks again. The steam generation performance of the recovered GA@Fe(III)@PVDF can remain stable over 150 degrading and recoating cycles. We believed that this work could offer opportunities to fabricate low-cost, sustainable, and degradable photothermal coatings for solar steam generation.
