Abstract
Ultrathin fluoroacrylic emulsion coating wrapped effective microporous non-woven air filtration membranes of 0.2 μm thickness were made for PPE masks with up to 99.9% filtration efficiencies for both 0.3 μm NaCl aerosol particles and oily DEHS aerosols. An ultrasonic dip-coating process was applied for the controllable formation of a nano-protrusion morphology on the fiber surface.
摘要
制备了超薄氟丙烯酸乳液涂层包裹的有效微孔非织造空气过滤膜，用于个人防护装备（PPE）口罩，对0.3μm氯化钠气溶胶颗粒和油性癸二酸二（2-乙基己基）酯（DEHS）气溶胶的过滤效率高达99.9%。采用超声浸涂工艺在纤维表面可控形成纳米突起形态。
