Air pollution, especially particle matter (PM) has caused serious damage to the environment and human health. Recently, polymer nanofiber air filter materials that can effectively remove PM have become one research hotspot. However, fabrication of with excellent removal efficiency at high temperatures is still a challenge. Herein, poly(m-phenyleneisophthalamide)/TiO2 (PMIA/TiO2) composite membrane superior for PM2.5 temperature stability was developed. The TiO2 nanoparticles were selected add into PMIA spinning solution in order regulate structure performance PMIA/TiO2 membrane. roughness exhibited filtration 99.3% pressure drop 61 Pa. Furthermore, benefiting from thermal TiO2, stability. remained stable after being subjected conditions (up 250 °C). This indicates great potential when applied under conditions.

Respiratory masks are the primary and most effective means of protecting individuals from airborne hazards such as droplets particulate matter during public engagements. However, conventional electrostatically charged melt-blown microfiber typically require thick dense membranes to achieve high filtration efficiency, which in turn cause a significant pressure drop reduce breathability. In this study, we have developed multielectrospinning system address issue by manipulating pore structure nanofiber networks, including use uniaxially aligned nanofibers created via an electric-field-guided electrospinning apparatus. contrast common randomly collected membranes, partially dual-nanofiber fabricated random 150 nm base layer 450 spacer on roll-to-roll collector, offer efficient way modulate membrane structures. Notably, configuration with submicron exhibits increased fiber density decreased volume density, resulting enhanced efficiency over 97% 50% reduction drop. This leads highest quality factor 0.0781. Moreover, within networks introduces additional sieving mechanism, ensuring superior under highly humid conditions even after washing 70% ethanol solution. The mask provides sustainable solution for safeguarding human respiratory system, it effectively filters inactivates coronaviruses while utilizing 130 times fewer polymeric materials than filters. reusability our their minimum usage would significantly plastic waste global society.

This study aims to prepare natural biomass-based nonionic antimicrobial polymers with excellent biocompatibility, nonleachability, activity, and polymer miscibility. Two new cellulose-based (MIPA MICA) containing many terminal indole groups were synthesized using a sustainable one-pot method. The structures properties of the characterized nuclear magnetic resonance hydrogen spectroscopy (1H NMR), infrared (FTIR), wide-angle X-ray diffractometry (XRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), electron microscopy (SEM), gel chromatography (GPC), other analytical techniques. results showed that microcrystalline cellulose (MCC) molecules combined derivatives through an esterification reaction produce MICA MIPA. crystallinity prepared MIPA decreased after MCC modification; their morphological structure changed from short fibrous granular better thermal stability solubility. paper diffusion method both had good bactericidal effects against two common pathogenic bacteria Escherichia coli (E. coli, inhibition zone diameters >22 mm) Staphylococcus aureus (S. aureus, >38 mm).

COVID-19 disease, triggered by SARS-CoV-2 virus infection, has led to more than 7.0 million deaths worldwide, with a significant fraction of recovered infected people reporting postviral symptoms. Smart surfaces functionalized nanoparticles are powerful tool inactivate the and prevent further spreading disease. Literature reports usually focus on role nanomaterial composition size dispersion in evaluating their efficacy against SARS-CoV-2. Here, anti-SARS-CoV-2 activity oleylamine (OAm) used as capping agent silver is quantified for first time. Spherical hydrophobic 8 ± 2 nm diameter were prepared characterized Fourier transform infrared, dynamic light scattering, transmission electron microscopy techniques. Biological assays showed that microgram amounts nanoparticles, deposited nonwoven textile obtained from surgical masks, efficiently inactivated up 99.6(2)% just min exposure. The virucidal corresponding amount free OAm been determined well, reaching 67(1)% an exposure time 10 min.
