【Abstract】 The treatment of polypropylene(PP)surfaces is studied by dielectric barrier discharger plasma of CO2+monomers.The structure and morphology of PP surfaces of monomers plasma modification is characterized by X-ray photoelectron spectroscopy,Fourier transform infrared spectrometers and scanning electron microscope.The free radical on modification surface of PP is analyzed by chemical method.The active PP which is modified can induce grafting coplymerization of monomers onto PP,and the plasma polymers from monomers are deposited in molten PP.The structure of grafting copolymer is characterized and the grafting percent of monomers onto PP is calculated.The oligomer of monomers or monomers are mixed into blending system of PP with plasma polymers,it follows that the alloying of PP with monomers is achieved in-situ.更多还原
