“…Similarly, the SA is the measurement of the water droplets' adhesion on the membrane surface. The lower the SA, the higher the membrane hydrophobicity 111. The value SA generally varies from 9° to 23°.…”

“…The membrane surface modification will help in increasing the surface roughness by creating air pockets on the membrane surface; consequently, the membrane hydrophobicity rises [111]. The surface roughness can be improved by creating a re-entrant or hierarchical structure with different additives, such as NPs.…”

Membrane distillation (MD), a temperature‐driven membrane separation process, is used for various applications due to its less complicated design. MD operations encounter major issues such as permeate flux decrease, membrane fouling, and wetting. A lot of research has been conducted in the past years on the modification of MD membranes by incorporating nanomaterials to overcome these obstacles and considerably increase their performance. Nanomaterials incorporated into the membranes improve the water permeability, mechanical strength, and fouling. The incorporation of next‐generation nanomaterials like metal oxide nanoparticles, carbon‐based nanomaterials, graphene‐based membranes, quantum dots, and metal‐organic frameworks in the MD membranes is investigated. Essential membrane properties for MD operations are comprehensively studied, including higher liquid entry pressure, permeability, porosity, hydrophobicity, thermal stability, mean pore size, and low fouling rate. Significant advances in the application of nanomaterials to the modification of MD membranes as well as other membrane fabrication techniques adopted for the incorporation of nanoparticles like surface grafting, interfacial polymerization, plasma polymerization, and dip coating are reviewed. Important future aspects are discussed.

“…Additionally, the membrane must be hydrophilic to promote the slipover of liquid on top of the fabric. There are several techniques that may be used to produce hydrophilic/phobic and breathable membranes, including melt-blowing, phase separation, template methods, fiber fibrillation, and electrospinning [5][6][7][8]. Due to the microporous nanofibrous structure produced through the aggregation of fibers, electrospinning has been shown to be a successful strategy for generating multifunctional protective clothing.…”

“…The scientific community interested in membrane technology is now much more aware of the damaging consequences that petroleum-based polymers have on the earth and human health. Biodegradable polymers have recently attracted substantial interest as appealing substitutes for petroleum-based polymers due to their biocompatibility and environmental benefits [7,18]. One of the most promising and sustainable nanofibrous materials for use in protective clothing is PLA, a biopolymeric hydrophobic thermoplastic material with exceptional resilience, elasticity, and UV resistance.…”

A perfect protective fabric for handicapped individuals must be lightweight, waterproof, breathable, and able to absorb water. We present a multifunctional protective fabric in which one side is hydrophobic based on the intrinsic hydrophobic biopolymer polylactic acid (PLA) to keep the disabled person from getting wet, while the other side is super-hydrophilic due to embedded silica nanoparticles (NPs) to keep the disabled person safe from a sudden spill of water or other beverage on their skin or clothes. The porosity of the electrospun nanofibrous structure allows the fabric to be breathable, and the silica NPs play an important role as a perfect infrared reflector to keep the person’s clothing cool on warm days. Adding white NPs, such as silicon dioxide, onto or into the textile fibers is an effective method for producing thermally insulated materials. Due to their ability to efficiently block UV light, NPs in a network keep the body cool. Such a multifunctional fabric might be ideal for adult bibs and aprons, outdoor clothing, and other amenities for individuals with disabilities.

“…Up to now, several electrospun nanofibers have been fabricated from a wide variety of polymeric materials, including a polymer/inorganic nanocomposite based on both natural and synthetic polymers [ 13 , 14 , 15 ]. Nanosensors [ 16 , 17 ], controlled drug delivery systems [ 18 , 19 , 20 , 21 , 22 ], wound healing [ 23 , 24 , 25 ], tissue engineering [ 26 , 27 , 28 ], energy devices [ 29 ], filtration [ 30 , 31 ], distillation [ 32 , 33 ], and the determination of environmental pollutants and photocatalysts [ 34 , 35 ] are some of the applications of electrospun nanofibers and nanofibrous membranes. Today, electrospun nanofibers incorporated with antibacterial agents are widely used for antimicrobial applications due to their enhanced antimicrobial performance compared to traditional antimicrobial materials [ 36 ].…”

Antimicrobial Activities of Polyethylene Terephthalate-Waste-Derived Nanofibrous Membranes Decorated with Green Synthesized Ag Nanoparticles

Thermoplastic polymers are one of the synthetic materials produced with high tonnage in the world and are so omnipresent in industries and everyday life. One of the most important polymeric wastes is polyethylene terephthalate (PET), and the disposal of used PET bottles is an unsolved environmental problem, and many efforts have been made to find practical solutions to solve it. In this present work, nanofibrous membranes were produced from waste PET bottles using the electrospinning process. The surface of membranes was modified using NaOH and then decorated with green synthesized Ag nanoparticles (10 ± 2 nm) using an in situ chemical reduction method. The morphology, size, and diameter of the Ag nanoparticles decorating the nanofibers were characterized through transmission electron microscopy (TEM), a field emission scanning electron microscope (FESEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and UV-visible spectroscopy techniques. Finally, the antimicrobial activity of the nanofibrous membranes was tested against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus using disc diffusion and colony-forming count methods. The growth of bacteria was not affected by the pure nanofibrous membranes, while the Ag-decorated samples showed inhibition zones of 17 ± 1, 16 ± 1, and 14 ± 1 mm for Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus, respectively. The planktonic culture results of Pseudomonas aeruginosa showed that the membranes had a relatively low inhibitory effect on its growth. The obtained results showed that Pseudomonas aeruginosa has a relatively low ability to form biofilms on the nanostructured membranes too. A good agreement was observed between the data of biofilm formation and the planktonic cultures of bacteria. The plastic-waste-derived PET/Ag nanocomposite membranes can be used for wound dressings, air filters, and water purification applications.
