Particulate air pollution is a global environmental problem, with PM being the primary pollutant. One of the most effective ways to remove particles from the air is through filtration. Therefore, high-performance air filters are urgently needed to combat the harm caused by PM. This study uses an electrospinning technique to prepare high-efficiency polyvinylidene fluoride/graphene oxide/polyimide nanofiber membranes. These composite nanofiber membranes demonstrate high filtration efficiency (99.6%), low pressure drop (123 Pa), remarkable thermal stability (450 °C), and excellent mechanical strength (7 MPa). Considering the advantages, these highly efficient nanofiber membranes can find advanced applications in industrial and civil infrastructures.
颗粒物空气污染是一个全球性的环境问题，其中细颗粒物是主要污染物。从空气中去除颗粒的最有效方法之一是通过过滤。因此，迫切需要高性能空气过滤器来对抗细颗粒物造成的危害。本研究采用静电纺丝技术制备了高效聚偏氟乙烯/氧化石墨烯/聚酰亚胺纳米纤维膜。这些复合纳米纤维膜具有高过滤效率（99.6%）、低压降（123帕斯卡）、显著的热稳定性（450℃）和优异的机械强度（7兆帕斯卡）。鉴于这些优点，这些高效纳米纤维膜可在工业和民用基础设施中找到先进的应用。
