Poly(tert-butyl acrylate) (PtBA) bruhes were successfully grafted on the cellulose filter papers via surface-initiated atom transfer radical polymerization (ATRP). Then the grafting PtBA brushes were transferred into poly(acrylic acid) (PAA) in the presence of trifluoroactic acid (TFA), which can form chelate complexes with Ag+. The Ag+ was reduced in situ to obtain the silver nanoparticles decorated cellulose filter papers. Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were used to characterize the chemical structure of the resulting product. The morphologies of the filter paper at different stages of surface modification were investigated by field emission scanning electron microscopy (FESEM). The silver nanoparticles decorated filter paper performed good antibacterial ability against E. coli as compared with the original filter paper and PAA modified filter paper.
