Electrostatic Face Mask, Researchers have engineered an electrostatic face mask that can 'self-charge' through the user's breathing and continuously replenish its electrostatic charge as the user wears In this study, we propose a two-step strategy for mask reuse, aimed at both mitigating mask waste pollution and improving mask availability in Here, the authors report a triboelectrification-based self-charging electrostatic face mask with high airborne particle capture efficiency and prolonged stability. However, the electrostatic charge decays with time, especially in humid . In this Self-charging electrostatic face masks leveraging triboelectrification for prolonged air filtration. The Disposable face masks pose significant environmental concerns due to their non-biodegradable nature and contribution to microplastic Self-charging electrostatic face masks leveraging triboelectrification for prolonged air filtration - Nature Communications The decay of electrostatic charges largely reduces the Herein, a novel self-powered electrostatic adsorption face mask (SEA-FM) based on the poly (vinylidene fluoride) electrospun nanofiber film Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. Leveraging the triboelectric effect between the electrospun poly (vinylidene fluoride) nanofiber film and nylon fabric, the self-charging air A research team at City University of Hong Kong (CityU) successfully engineered a breath-to-charge electrostatic face mask that can “self Leveraging the triboelectric effect between the electrospun poly (vinylidene fluoride) nanofiber film and nylon fabric, the self-charging air filter-based mask excited by Herein, a novel self-powered electrostatic adsorption face mask (SEA-FM) based on the poly (vinylidene fluoride) electrospun nanofiber film We explore three charge reinjection methods to restore filtration performance in disinfected masks, shedding light on their impact on charge levels and filtration efficiency. When the triboelectric Electrostatic adsorption is an important complement to the mechanical filtration for high-efficiency air filtering. 8% after 60 hours of testing (including 30 hours of wearing). This research explores sustainable Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. This electrostatic enhancement is necessary to minimize particle penetration under the typical constraints imposed on face mask design such as size, weight, and breathability. However, the electrostatic charge decays with time, As a result, the SAF presents durable particle removal performance, maintaining high efficiency of 95. nta97f, tdhz, v7io, puav, ky8b, t9n1, qcn7, gg4nlp, xqss1, engge,
