A novel filtration of cigarette smoke prepared by two steps grafting of AA and AMPS monomer onto PP matrix

In order to improve the poor adsorption for cigarette smoke and tar of polypropylene (PP) fiber, AA and AMPS were grafted onto PP fiber matrix by two steps plasma irradiation grafting for preparation a novel composite filtration of cigarette smoke PP-g-(AA+AMPS). The factors influenced the grafting degree were discussed, such as the irradiation time, concentration of monomer and the concentration of inhibitor. Attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FT-IR) and scanning electron microscopy (SEM) were used to characterize the chemical and morphological changes of the original and grafted PP fiber matrix, the results indicated that AMPS was grafted onto the surface of PP fiber matrix. The results indicated that the filtration efficiency of PP fiber was improved significant after graft modification, the total particulate matter in mainstream cigarette smoke reduces 30.5%, and the concentration of tar and nicotine are decrease 43.2% and 31.7%, respectively.
