Abstract: In order to investigate the adsorption properties of graphene oxide (GO) on PM2.5,GO films based on four different non-woven fabrics were prepared by spraying method,and their adsorption properties and long-term effectiveness were tested.The samples were characterized by scanning electron microscopy,raman spectroscopy,X-ray diffraction and Infrared spectroscopy.The results shown that GO was adhered to the surface of the non-woven fabric and formed a film between the fibers.The GO material had the adsorption property to PM2.5 and the effect was obvious.The GO film removal efficiency on different substrates were 34%,95%,45%,and 82%,respectively,which increased by 27%,5%,30%,and 28%.After 15 days of continuous measurement,the removal of PM2.5 by GO film maintained good stability and long-term effectiveness.
