Sustainable trans-scale fibrous membranes for stable ultra-protective air filtration (opens in new tab)

Disposable fibrous air filtration media represent one of the most convenient and effective approaches for personal health protection. Nevertheless, restricted by the technical bottlenecks of spinning technologies in fabricating ultrafine nanofibers and designing topological filtration networks, current filters cannot realize reliable ultra-protection against ultrafine particulate matter (PM). Moreover, non-degradable waste from excessive filter use imposes severe environmental burdens. Herein...
