Preparation of PVDF Antibacterial Nanofibermembrane and Its Air Filtration Performance
The influence of the ratio of N,N-dimethylformamide and acetone on the solubility of iodine-containing organic antimicrobial agents was discussed,and the polyvinylidene fluoride nanofiber antibacte-rial membrane with good antibacterial properties against Staphylococcus aureus and Escherichia coli was prepared.By adjusting the winding speed of the rolling bearings in the winding device,polypropylene based polyvinylidene fluoride nanofiber composite materials with different resistance pressure drop and air filtra-tion performance were obtained.The optimal filtration efficiency was determined to reach 99.81%.Taking into account the resistance pressure drop,the optimal quality factor can reach 0.0112,which has the po-tential to filter particulate pollutants in the air.
