Fiber has been considered as an ideal material for virus insulation due to the readily available electrostatic adsorption. However, restricted by attenuation and filtration performance decline, their long-lasting applications are unable satisfy requirements of medical protective equipment major health emergencies such global epidemics, which results in both a waste resources environmental pollution. We overcame these issues constructing fiber-in-tube structure, achieving robust reusability fibrous membranes. Core fibers within hollow could form generators with tube walls shell provide persistent, renewable static electricity via piezoelectricity triboelectricity. The PM0.3 efficiency achieved 98% even after 72 h humidity heat aging, through beating acoustic waves, is greatly improved compared that traditional nonwoven fabric (∼10% insulation). A mask spun our fiber also low breathing resistance (differential pressure <24.4 Pa/cm2). offer approach enrich multifunctional developing electrifiable filters, make membrane able durably maintain higher level reduce replacement new train thought preparation other high-performance products.
