Abstract Currently, multifunctional MXene‐integrated wearable textiles (MWTs) are particularly appealing due to their various applications such as health monitoring, smart protection, and medical treatment. However, scalable manufacture of durable, stable, high‐performance MWTs still face challenges the poor oxidation stability MXene low utilization precursor titanium aluminum carbide (MAX). Herein, an improved preparation strategy for zinc ion (Zn 2+ ) intercalation is proposed create high...
Fluffy electret polypropylene/magnesium stearate materials may become good candidates for personal protective filtration against PM2.5.
Despite the tremendous efforts on developing antibacterial wearable textile materials containing Ti3C2Tx MXene, singular antimicrobial mechanism, poor durability, and oxidation susceptibility of MXene limits their applications. In this context, flexible multifunctional cellulosic textiles were prepared via layer-by-layer assembly in-situ synthesis zeolitic imidazolate framework-8 (ZIF-8). Specifically, introduction highly conductive enhanced interface interactions between ZIF-8 layer...
The demand for air filtration materials in recent years has been substantially increasing on a worldwide scale because people are paying extensive attention to particulate matter (PM) pollution. In this work, we report type of needle-punched triboelectric filter (N-TAF) consisting polytetrafluoroethylene (PTFE) fibers modified by silica nanoparticles and polyphenylene sulfide (PPS) fibers. Compared conventional electrostatic precipitators, the N-TAF can be charged online unique nonwoven...
Electret filters are widely used in particulate matter filtration due to their efficiency that can be greatly improved by electrostatic forces without sacrificing the air resistance. However, attenuation of remains a challenge. In this study, we report novel strategy for producing an electret melt blown filter with superior stability through thermally stimulated charging method. The proposed approach optimizes crystal structure and therefore results increased production probability charge...
Particulate matter (PM) and airborne viruses bring adverse influence on human health. As the most feasible way to prevent inhalation of these pollutants, face masks with excellent filtration efficiency low press drop are in urgent demand. In this study, we report a novel methodology for producing high performance air filter by combining melt blown technique corona charging treatment. Changing crystal structure polypropylene adding magnesium stearate can avoid charge escape ensure stability...
Three-dimensional fluffy air filtration materials with low resistance and ultra-high dust holding capacity were fabricated by a bicomponent spunbond technique.
ABSTRACT Air pollution has seriously threatened public health in developing countries. However, it is still a big challenge for fabricating filter with high filtration efficiency, low air resistance, and long service life. Herein, we report facile strategy to fabricate multilayered nonwoven composite functionally gradient structure by combined method of needle‐punch, melt blown, corona charging techniques. Our integrated multilayer needle‐punched/melt blown could achieve efficiency up 99.52...
As derivatives from marine natural biomaterials, alginate-based and chitosan-based biomaterials are commonly used in wound dressings. Calcium alginate fiber (CAF) dressings possess excellent absorption unique gel forming performance, but the low bioactivity limits its application healing. Carboxymethyl chitosan (CM-Chit) has antibacterial activity, structure with weak mechanical properties restricts application. In this study, minocycline (Mino)/CM-Chit solution was coated on surface of...
ABSTRACT In recently years, fine particulate matter (PM) pollution has drawn worldwide attention due to its serious threat public health, visibility, climate, and ecosystems. The electret filter that can significantly improve the filtration efficiency without increasing pressure drop been widely used for PM filtration. However, there were still some blind spots in corona charging process, such as interaction effects between factors on performances electric spark phenomenon during charging,...
Abstract Smart windows that both reversibly occlude visible light and modulate the penetration of near‐infrared (NIR) save a great deal energy. Here, simple, super‐fast, electrically switchable smart window initially reflects NIR then scatters it in response to thermal stimuli is designed fabricated. Transparent polymer‐stabilized cholesteric liquid crystals (PSCLCs) are prepared by photo‐polymerizing RM 257 monomers which planar CLCs fully reflected (1050–1550 nm). Next, an ultra‐thin,...
With the aim of controlling problem fine particles in flue gas lead-zinc smelting, a low-temperature plasma-electrocoagulation and electric bag composite dedusting experimental platform was designed by combining electrocoagulation dust removal technology based on research plasma technology. Firstly, properties from smelting were analyzed, effects input voltage, filter wind speed, concentration, pulse-jet ash-cleaning cycle collection efficiency integrated device studied. Then, energy control...
Wet-laid hydroentangled nonwovens are widely used for disposable products, but these products generally do not have good dispersibility and can block sewage systems after being discarded into toilets. In this study, both pulp fibers Danufil selected as we hypothesize that the high wet strength striated surface of would allow us to produce with better while having enough mechanical properties. The systematically studied by investigating influence fiber blend ratio, length, water jet pressure....

In block, novel phase detector combines tasks of sampling charge-pump using half rate clock. Starting-control can ensure CDR takes full use provided by voltage line. Moreover, fully analog DLL technique applied...
The protection effects of wearing masks against viruses and bacteria have been verified many times over previous pandemics infectious diseases. However, the supply surgical can barely meet surging demand at early stage (first 12 months) outbreak a pandemic. Thus, it is essential to use wisely in such urgent times. In this work, we selected two types systematically explored how actual time influences protective performances masks. Each type was worn for 4, 10, 24, 32 48 h, respectively,...
