In this paper, grafted polyacrylamide from the surface of glass fibers was prepared by surface initiated atom transfer radical polymerization in order to control the matrix surface structure and properties. The uniform and stable grafted polymer layer was utilized to prepare silver ions complexes, and then the silver ions were reduced by AlLiH4 to form in situ silver nanoparticles. The structure, composition, properties and surface morphology of the modified glass fibers were characterized by X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, thermo gravimetric analysis and scanning electron microscopy. The antibacterial activities of modified glass fibers against E. coli, B. subtilis and S. cerevisiae had been studied respectively by Shake Flask Method. The results show that the antibacterial ratio of Ag nanoparticles loaded glass fibers is significantly improved than that of Ag+ loaded, and the highest antibacterial ratio is 72.2% against E. coli.
