Chitosan( CS) was used to graft onto pretreated PET fibers by sol-gel method. The transformations of surface chemical structure,microcosmic morphology and thermodynamic property were investigated by Fourier transform infrared spectroscopy( FTIR),X-ray photoelectron spectroscopy( XPS), scanning electron microscope( SEM), X-ray diffraction technique( XRD), and thermo gravimetric analysis( TGA),respectively. The wettability and antistatic property of PET fiber were significantly improved after modification by SE and CS.展开更多
