The contamination of water resources is a significant environmental challenge. The creation of innovative technologies to address this challenge is of paramount significance. Nanomaterials within polymeric membranes have surfaced as a hopeful technology within the realm of water purification, offering solutions to crucial issues concerning the elimination of pollutants and pathogens from water supplies. The exceptional properties of nanomaterials within polymeric membranes, including their high surface area, tunable pore sizes, and selective permeability, have enabled significant progress in the effective removal of various contaminants from water. This is due to the integration of nanoscale materials, such as metal nanoparticles, nanofibers, graphene, and graphene oxide, which has further enhanced the membrane performance by introducing enhanced mechanical strength, improved separation efficiency, and increased adsorption capacities. Recent research has focused on tailoring nanomaterials within polymeric membranes to target specific contaminants, such as viruses, bacteria, heavy metals, organic pollutants, and microplastics. Functionalization techniques, such as surface modification and incorporation of specific functional groups, have been employed to enhance the adsorption and separation capabilities of these membranes. Moreover, innovative fabrication methods, including layer-by-layer assembly, electrospinning, and template-assisted techniques, have been explored to achieve precise control over membrane properties and morphology. This review provides an overview of the current status and advancements in the utilization of nanomaterials within polymeric membranes for water purification applications.
