Electrospun porous nanofibers have large specific surface areas and abundant active centers, which can effectively improve the properties of nanofibers. In field photocatalysis, electrospun increase contact area loaded photocatalytic particles with light, shorten electron transfer path, activity. this paper, main pore−forming mechanisms nanofiber are summarized as breath figures, phase separation (vapor−induced separation, non−solvent−induced thermally induced separation) post−processing (selective removal). Then, application loading in degradation pollutants (such organic, inorganic, bacteria) water is introduced, its future development prospected. Although structures beneficial improving performance nanofibers, they reduce their mechanical properties. Therefore, strategies for also briefly discussed.

The outbreak of COVID-19 provided a warning sign for society worldwide: that is, we urgently need to explore effective strategies combating unpredictable viral pandemics. Protective textiles such as surgery masks have played an important role in the mitigation pandemic, while revealing serious challenges terms supply, cross-infection risk, and environmental pollution. In this context, with antivirus functionality attracted increasing attention, many innovative proposals exciting commercial possibilities been reported over past three years. review, illustrate progress textile filtration pandemics summarize recent development antiviral personal protective purposes by cataloging them into classes: metal-based, carbon-based, polymer-based materials. We focused on preparation routes emerging textiles, providing forward-looking perspective their opportunities challenges, evaluate efficacy, scale up manufacturing processes, expand high-volume applications. Based conclude ideal are characterized high efficiency, reliable effect, long storage life, recyclability. expected processes should be economically feasible, scalable, quickly responsive.

Bioelectrets in Electrospun Bimodal Poly(lactic acid) Fibers: Realization of Multiple Mechanisms for Efficient and Long-Term Filtration of Fine PMs

ACS Applied Materials & Interfaces, Год журнала: 2023, Номер 15(21), С. 25919 - 25931

Despite the great potential in fabrication of biodegradable and eco-friendly air filters by electrospinning poly(lactic acid) (PLA) membranes, filtering performance is frequently dwarfed inadequate physical sieving or electrostatic adsorption mechanisms to capture airborne particulate matters (PMs). Here, using parallel spinning approach, unique micro/nanoscale architecture was established conjugation neighboring PLA nanofibers, creating bimodal fibers electrospun membranes for enhanced slip effect significantly reduce resistance. Moreover, bone-like nanocrystalline hydroxyapatite bioelectret (HABE) exploited enhance dielectric polarization properties PLA, accompanied controlled generation junctions induced microaggregation HABE (10-30 wt %). The incorporated supposed orderly align applied E-field largely promote charging capability surface potential, gradually increasing 7.2 kV from lowest level 2.5 pure PLA. This mainly attributed HABE-induced orientation backbone chains C═O dipoles, as well interfacial charges trapped at interphases HABE-PLA crystalline region-amorphous Given multiple capturing mechanisms, micro/nanostructured PLA/HABE were characterized excellent sustainable performance, e.g., filtration efficiency PM0.3 promoted 59.38% 94.38% after addition 30 % a moderate airflow capacity 32 L/min 30.78 83.75% highest 85 L/min. It interest that pressure drop decreased, arising between ultrafine nanofibers conjugated microfibers. proposed combination nanostructured electret multistructuring strategy offers function integration efficient low resistance are highly useful pursue fully filters.

Ultrathin, ultralight dual-scale fibrous networks with high-infrared transmittance for high-performance, comfortable and sustainable PM0.3 filter

Nature Communications, Год журнала: 2024, Номер 15(1)

Abstract Highly permeable particulate matter (PM) can carry various bacteria, viruses and toxics pose a serious threat to public health. Nevertheless, current respirators typically sacrifice their thickness base weight for high-performance filtration, which inevitably causes wearing discomfort significant consumption of raw materials. Here, we show facile yet massive splitting eletrospinning strategy prepare an ultrathin, ultralight radiative cooling dual-scale fiber membrane with about 80% infrared transmittance high-protective, comfortable sustainable air filter. By tailoring antibacterial surfactant-triggered charged jets, the fibrous filter consisting continuous nanofibers (44 ± 12 nm) submicron-fibers (159 32 is formed. It presents ultralow (1.49 μm) (0.57 g m −2 ) but superior protective performances (about 99.95% PM 0.3 removal, durable ability) comfort low resistance, high heat dissipation moisture permeability. Moreover, save over 97% polymers than commercial N95 respirator, enabling itself be economical. This work paves way designing advanced
