▎ 摘  要

NOVELTY - Polytetrafluoroethylene composite filter material comprises a supporting layer and a polytetrafluoroethylene microporous film layer, where the supporting layer is a silver-plated carbon nano material modified melt-blown non-woven fabric. USE - The polytetrafluoroethylene composite filter material is useful for air purification by filtering PM2.5 containing bacteria and virus aerosol and other fine particles. ADVANTAGE - The polytetrafluoroethylene composite filter material: has high filtering efficiency and high filtering precision, has sterilizing effect, high resistance to bacteria and virus, good ventilation property and good absorption performance; and is suitable for human health requirements.
