Since the beginning of the COVID-19 pandemic, several attempts have been made worldwide to control the spread of the virus. It is widely accepted that wearing face masks in public and workplaces suppresses the transmission of the virus. Highly effective face masks, e.g. N95, have a high filtration efficiency but with a large pressure drop, which does not allow one to wear the mask comfortably for long hours. A larger population wearing a moderate efficiency mask can also cut the transmission at large. Herein, mask panels from readily available fabrics are developed, that can generate triboelectricity, which enhances the filtration efficiency by around 18% without compromising the pressure dropâ€”allowing one to wear the mask for an extended period. The unique cup-shaped design of the mask provides a snug fit with no speech distortion or fogging on the glasses.

美观、呼吸友好的摩擦电面罩：设计、制造及其功效

自 COVID-19 大流行开始以来，世界范围内已多次尝试控制病毒的传播。人们普遍认为，在公共场所和工作场所戴口罩可以抑制病毒的传播。高效口罩，如N95，过滤效率高，但压降大，无法长时间舒适佩戴。戴上中等效率口罩的更多人口也可以减少传播。在这里，开发了由现成的织物制成的面罩面板，可以产生摩擦电，在不影响压降的情况下将过滤效率提高约 18%——允许人们长时间佩戴面罩。
