Experimental analysis demonstrates accelerated degradation and antibacterial activity in Ag-MOF composite membranes, suggesting viable eco-friendly filters.
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.
