“…Obviously, the 2E/1C membrane had the highest filtration efficiency and the lowest pressure drop; because it had a uniform and smallest fiber diameter and a certain bead structure, the former improved the interception of particles while the latter provided more space for the air flow to pass through. 32,52 In contrast, the 2E/1D membrane exhibited the worst filtration efficiency and the highest pressure drop due to its poor fiber morphology and largest diameter. Therefore, the well-shaped cylindrical morphology, a certain bead structure, and a smaller fiber diameter jointly improved the air filtration performance.…”

Biobased high-performance air filters via green electrospinning are the key to reducing the energy crisis and the environmental burden. However, the complicated postprocessing limits its application. In this research, a green solution system with delayed volatilization was constructed, and a zein/cinnamaldehyde (CMA) composite nanofibrous membrane with optimized structure was produced by one-step electrospinning. The addition of CMA significantly decreased the volatility of the solution, deferring the clogging time of the nozzle and thus smoothing the electrospinning process. The time from the start of electrospinning to nozzle blockage increased by over 300%, resulting in a significant improvement in fiber morphology. The air filtration efficiency for PM0.3, the pressure drop, and the quality factor were 99.25%, 58.2 Pa, and 0.084 Pa–1, respectively, compared to the membrane without CMA addition and N95 mask. Moreover, the CMA improved the hydrophobicity of the zein nanofiber, which helped improve the stability of air filtration and endowed the nanofibers with certain antibacterial properties. This work is the first to report that CMA improves continuity in electrospinning, which will promote the development of green electrospinning and the preparation of a high-performance biobased air filter.

“…Compared to synthetic electrets, naturally charged polymers are most promising for long-lasting air filtration, as they can achieve high electrostatic adsorption without recharging and regeneration. − Chitosan is a charged natural polymer with promise for long-lasting air filtration. Chitosan comprises N -acetyl- d -glucosamine and β-(1–4)-linked d -glucosamine with a highly stable distribution of naturally positively charged groups on its backbone. − The ionizable amino and hydroxyl groups of chitosan facilitate the binding of negatively charged particles in the air and can improve the filtration efficiency of chitosan-based filters. − Moreover, the positive charge of chitosan interacts with the envelope proteins of viruses, disrupts viruses’ structure, or interferes with their replication. − For example, Hathout and Kassem suggested that the application of positively charged chitosan or poly- l -lysine fibers in personal protective masks or protective clothing could reduce the viral load by exploiting the electrostatic repulsion between the fibers and SARS-CoV-2 (Figure c) . Recently, Zhang et al used hot air chitosan fibers as an antiviral layer for masks, and the chitosan fibers’ electrostatic effect reduced the activity of enterovirus 71 (EV71, which can be transmitted through the respiratory tract) .…”

Air-transmitted pathogens may cause severe epidemics, posing considerable threats to public health and safety. Wearing a face mask is one of the most effective ways to prevent respiratory virus infection transmission. Especially since the new coronavirus pandemic, electroactive materials have received much attention in antiviral face masks due to their highly efficient antiviral capabilities, flexible structural design, excellent sustainability, and outstanding safety. This review first introduces the mechanism for preventing viral infection or the inactivation of viruses by electroactive materials. Then, the applications of electrostatic-, conductive-, triboelectric-, and microbattery-based materials in face masks are described in detail. Finally, the problems of various electroactive antiviral materials are summarized, and the prospects for their future development directions are discussed. In conclusion, electroactive materials have attracted great attention for antiviral face masks, and this review will provide a reference for materials scientists and engineers in antiviral materials and interfaces.

“…Combining two or more polymers with different properties has been reported as a successful strategy for the obtainment of nanofibrous membranes with high filtration performance due to the possibility of combine the respective strengths. [104] Wang et al, [40] for example, fabricated porous nanofibers using a PVP/PTFE blend in which PVP was used as a sacrificial phase. Thanks to the extremely porous nanofibrous membrane high filtration efficacy and ultralow pressure drop were achieved.…”

Air pollution is one of the major global problems causing around 7 million dead per year. In fact, a connection between infectious disease transmission, including COVID‐19, and air pollution has been proved: COVID‐19 consequences on human health are found to be more severe in areas characterized by high levels of particulate matter (PM). Therefore, after the COVID‐19 pandemic, the production of air filtration devices with high filtration efficiency has gained more and more attention. Herein, a review of the post‐COVID‐19 pandemic progress in nanofibrous polymeric membranes for air filtration is provided. First, a brief discussion on the different types of filtration mechanism and the key parameters of air filtration is proposed. The materials recently used for the production of nanofibrous filter membranes are presented, distinguishing between non‐biodegradable polymeric materials and biodegradable ones. Subsequently, production technique proposed for the fabrication of nanofibrous membranes, i.e., electrospinning and solution blow spinning, are presented aiming to analyze and compare filtration efficiency, pressure drop, reusability and durability of the different polymeric system processed with different techniques. Finally, present challenges and future perspectives of nanofibrous polymeric membranes for air filtration are discussed with a particular emphasis on strategies to produce greener and more performant devices.
