At the beginning of 2020, the whole world suffered from the new coronavirus (COVID-19). Wearing a mask was believed to reduce the spread of the virus. The core material of a mask required good air permeability and efficient filtration. Electrospun materials may match these requirements. By electrospinning, we prepared polyvinyl butyral (PVB)/berberine hydrochloride (BH) membranes onto the spunbonded nonwovens. The composite meshes showed porous structures, good air permeability (164 ± 16 mm/s) and air filtration efficiency 96.4% for PM 0.3, 100% for PM 2.5, with pressure drop (108 Pa). Moreover, with the addition of BH, the as-spun membranes showed good antibacterial property for staphylococcus aureus. Furthermore, the prepared PVB/berberine membranes had good hydrophobicity with water contact angle higher than 140°. These results indicated that the fabricated PVB/berberine membranes have potential applications in mask and air filtration. |
