Abstract: The development of purification materials has become a research focus towards air purification. Nanofiber membrane has showed great potentials in air purification due to its interconnected nanoscale pore structures. The filtration performance of nanofibrous air filter is usually characterized by both the filtration efficiency and the filtration resistance. The research progress of nanofiber membrane with different structure,such as bead-on-string,nanofiber/nets and composite is introduced,and the application status of electret nanofiber membrane used in efficient dust removal is reviewed. The feasibility on the application of silver nanoparticles or semiconductor metal oxide modified nanofiber membrane in multi-functional air purification,such as antibacterial and degradation of VOCs,is analyzed. High efficiency,low resistance and functionalization will be the key points for nanofiber membrane in air purification. It is expected that nanofibrous air purification membrane with multifunction will gain more and more applications in the future.
