| Summary: | With an emphasis on improving the membrane’s long-term durability and filtering efficiency, this study examines how well nanoparticle-modified polyvinylidene fluoride (PVDF) membranes perform in postponing membrane aging. The functionalization of PVDF membranes with mesoporous silica nanoparticles (MSNs) to increase their resistance to fouling and degradation makes this study novel. Sol–gel synthesis was used to create MSNs, which were then included in the PVDF membrane matrix. Brunauer–Emmett–Teller surface area analysis, X-ray diffraction, and scanning electron microscopy were used to analyze the structural characteristics of the modified membranes. The findings showed that adding MSNs improved the mechanical strength and permeability of the membrane by increasing its surface area and pore volume. Comparing the modified PVDF membranes to the unmodified membranes, aging tests revealed a slower drop in filtering performance and increased resilience to fouling and chemical degradation. According to these results, MSN-modified PVDF membranes are a promising material for water treatment and other filtering applications since they have a great deal of potential to increase the longevity and effectiveness of filtration systems. |
