Owing to the significant increase in air pollutants and the spread of infectious diseases,it seems that the use of face masks will be-come an essential item in human societies.Therefore,there is a need to conduct more research to develop novel types of respirators utilizing up-to-date science such as nanotechnology.In this study,we fabricated a nanocomposite fibrous filter containing modified graphene oxide(GO)and zinc oxide(ZnO)nanoparticles.This layer was used as an active filter for absorbing and removing air pollutants,such as suspended sub-micron particles(below 2.5 microns)and CO2,NO2,and SO2 gases.The synthesized nanostructures and fibrous filters were characterized by differ-ent analysis(FTIR,XRD,TGA,and FESEM),and the performance of the filters was surveyed by tests such as pressure drop,CO2,NO2,SO2 gas rejec-tion,and particulate removal.The results showed that the stabilization of the modified GO and ZnO nanostructures on the fibrous filter improved the effectiveness of this filter as a mask for removing toxic particles and gases,and the filter containing nanoparticles had the best performance.
