Large-Scale Nanofiber Manufacturing| Lotus leaf-inspired poly(lactic acid)nanofibrous membranes with enhancedhumidity resistance for superefficient PMfiltration and high-sensitivity passivemonitoring 2025-05-09

Particulate matter (PM) pollution in air poses significant challenges for modern society, severely damaging ecological environments, hindering precision manufacturing development, and even threatening human health. Due to their extremely small size and complex composition, PMs easily carry and spread bacteria and viruses, posing major risks to respiratory safety and cardiovascular systems. Biodegradable polylactic acid (PLA) nanofiber membranes (NFMs) show great potential in addressing increasing airborne PMs and plastic/microplastic pollution, but still suffer from poor electret effects, dielectric properties, and surface activity - especially rapid charge dissipation under high humidity, presenting challenges for long-term respiratory protection.
