Protection from particulate matter (PM₁₀ and PM_2.5) and microorganisms using MOFs (metal–organic frameworks) and nanoparticles used in filtration has been a major challenge. In this study, poly(vinylidene fluoride) (PVDF) nanofibers embedded with MOF-801 and Cu₂O nanoparticles were prepared using electrospinning. The modified nanofibers adsorb particulate matter (PM₁₀ and PM_2.5) and reduce microorganism populations, thereby improving filtration and antibacterial processes. The multifunctional nanomaterials, which are suitable for use in the presence of hazardous concentrations of particulate matter and E. coli because of the well-dispersed MOF-801 and Cu₂O on the nanofibers, show very efficient particulate matter adsorption (PM_2.5: 64.46%, PM₁₀: 63.19% after 5 min and PM_2.5: 88.26%, PM₁₀: 85.22% after 10 min, respectively).

包含金属有机骨架和Cu2O纳米粒子的多功能纳米纤维的制备和表征：颗粒物捕获和抗菌活性

使用MOF（金属有机框架）和用于过滤的纳米颗粒来保护免受颗粒物（PM ₁₀和PM _2.5）和微生物的侵害是一项重大挑战。在这项研究中，使用电纺丝制备了嵌有MOF-801和Cu ₂ O纳米粒子的聚偏二氟乙烯（PVDF）纳米纤维。改性的纳米纤维吸附颗粒物（PM ₁₀和PM _2.5）并减少微生物种群，从而改善过滤和抗菌过程。该多功能纳米材料由于MOF-801和Cu _2的分散性好，适合在危险浓度的颗粒物和大肠杆菌的情况下使用纳米纤维上的O表现出非常有效的颗粒物质吸附（5分钟后分别为PM _2.5：64.46％，PM ₁₀：63.19％和10分钟后PM _2.5：88.26％，PM ₁₀：85.22％）。
