Nowadays, a degradable membrane with efficient filtration and antibacterial properties needs to be studied and developed because of the limitations of the widely used melt-blown polypropylene (PP) nonwoven fabrics such as nondegradation and nonantibacterial. Herein, silver(I) metal–organic frameworks (Ag-BTC) were prepared with AgNO3 and trimesic acid (H3BTC) and embedded into a degradable blend of poly(l-lactide) (PLLA) and poly(butylene succinate) (PBS) to make a filtration and antibacterial membrane by electrospinning technology. The composite membrane had good filtration performance, and the antibacterial coil widths of PSAB1.8 were 2.039 mm for Escherichia coli and 1.322 mm for Staphylococcus aureus. The degradation behavior of prepared membranes in river and seawater was investigated in detail by scanning electron microscopy, Fourier transform infrared, and thermogravimetric analysis. The results indicated that the addition of Ag-BTC had a promoting effect on the degradation process of the membrane.

具有良好抗菌和过滤性能的静电纺Ag-MOF/PLLA/PBS膜在水中的降解行为



目前,由于广泛使用的熔喷聚丙烯(PP)非织造布存在不降解、不抗菌等局限性,亟待研究开发兼具高效过滤和抗菌性能的可降解膜。在此,用 AgNO 3 和均苯三酸 (H 3 BTC) 制备银 (I) 金属有机骨架 (Ag-BTC),并将其嵌入聚 (l) 的可降解混合物中。丙交酯(PLLA)和聚丁二酸丁二醇酯(PBS)通过静电纺丝技术制成过滤抗菌膜。复合膜具有良好的过滤性能,PSAB1.8对大肠杆菌的抗菌线圈宽度为2.039 mm,对金黄色葡萄球菌的抗菌线圈宽度为1.322 mm。通过扫描电子显微镜、傅里叶变换红外和热重分析详细研究了制备的膜在河流和海水中的降解行为。结果表明Ag-BTC的添加对膜的降解过程有促进作用。
