“…After that, these three layers were bonded together under a hot-pressing process (80 °C, 5 min). In the hot-pressing process, the bonding points were formed on the surface of composite fabrics, which ensured firm adhesion between each layer. − Finally, the obtained membranes were reinforced by ultrasonic bonding process, constructing a tighter fiber network with more bonding points. , We believe such a scalable laminating process holds promise for the production of high-throughput and lower-cost medical protective clothing.…”

The COVID-19 created severe shortages of prevention materials and supplies, and the reuse of medical protective clothing is ongoing worldwide. However, it has remained a significant challenge to realize the reusability of the current medical protective clothing. We reported a scalable strategy to create autoclavable ternary electrospun nanofibrous membranes (TENMs) by introducing the elastomer polyurethane (PU) and low-surface-energy fluorinated polyurethane (FPU) into poly(ether sulfone) (PES) fibers via electrospinning. The advantage of this design was that we could balance the waterproof-breathable function and the thermostable performance of the membrane by controlling the PES/PU/FPU mass ratio. The resulting TENMs showed excellent performances of a high moisture transmission rate of 8.3 kg m–2 day–1, a high hydrostatic pressure of 82.56 kPa, a high bacteria retention rate of 99.99%, a high aerosol retention rate of 99.99%, and autoclave sterilization-invariant to 10 cycles. The successful preparation of the material can lead to the reuse of medical protective clothing in the foreseeable future.

“…Due to the good processability of PET, PA, as well as PS, was processed by electrospinning and the conditions of production electrospun membranes have been already extensively described in the literature [35][36][37][38][39]. The randomly arranged ultrafine fibers in the electrospun membranes, the high surface area to volume ratios, nanoporosity, good mechanical properties, and vapor permeability of such membranes predestined them for filtration membranes and especially for personal protection as face masks against very fine dirt and bacteria, but also viruses with dimensions of about 100 nm [40,41].…”

Recent Developments in Nanofibers Research

Synthetic polymers have been widely applied in various commercial and household applications owing to their fascinating properties of low-cost, lightweight, and processability. However, increasing population and living standards and rising demand for non-biodegradable polymers have led to the accumulation of plastic pollution resulting in the current environmental crisis. Current waste management methods such as landfilling or incineration do not solve these environmental issues. On the other hand, recycling plastic waste is the most valuable strategy for dealing with waste as raw material for high-value products. One of such products is filter membranes. Polymer fiber membranes as masks in pandemics have been one of the most sought-after products in recent years. Some types of plastic waste became a material source for the development of filter materials, which could contribute to the protection of human health. Utilizing the simple, cheap, and industrially available technological solution is also needed. Given the number of advantages, electrospinning is such a beneficial solution. The electrospun polymer waste-based membranes show excellent filtration performance and can carry many other functionalities. Therefore, this review article presents a brief overview of electrospun nanofibrous membranes based on synthetic plastic waste and summarizes the filtration performance of such membranes. This review will discuss the future perspectives of electrospun membranes as well.

“…On that account, our work aimed to enhance the adhesion of PCL NFs to spunbond PP fabric modified by the radio-frequency (RF) low-pressure capacitively coupled plasma discharge and the low-temperature atmospheric-pressure RF plasma slit jet (PSJ) [ 40 , 41 ]. In a few studies [ 24 , 25 , 33 , 34 , 35 , 38 , 42 ], adhesion between NFs and textile support is evaluated, and all of them have employed tensile T-peel tests requiring a rather thick nanofibrous mat. Nevertheless, interest in fabricating thin nanofibrous mats that still retain functionality will grow due to the necessity of cost reduction.…”

Enhanced Adhesion of Electrospun Polycaprolactone Nanofibers to Plasma-Modified Polypropylene Fabric

Excellent adhesion of electrospun nanofiber (NF) to textile support is crucial for a broad range of their bioapplications, e.g., wound dressing development. We compared the effect of several low- and atmospheric pressure plasma modifications on the adhesion between two parts of composite—polycaprolactone (PCL) nanofibrous mat (functional part) and polypropylene (PP) spunbond fabric (support). The support fabrics were modified before electrospinning by low-pressure plasma oxygen treatment or amine plasma polymer thin film or treated by atmospheric pressure plasma slit jet (PSJ) in argon or argon/nitrogen. The adhesion was evaluated by tensile test and loop test adapted for thin NF mat measurement and the trends obtained by both tests largely agreed. Although all modifications improved the adhesion significantly (at least twice for PSJ treatments), low-pressure oxygen treatment showed to be the most effective as it strengthened adhesion by a factor of six. The adhesion improvement was ascribed to the synergic effect of high treatment homogeneity with the right ratio of surface functional groups and sufficient wettability. The low-pressure modified fabric also stayed long-term hydrophilic (ten months), even though surfaces usually return to a non-wettable state (hydrophobic recovery). In contrast to XPS, highly surface-sensitive water contact angle measurement proved suitable for monitoring subtle surface changes.
