摘　　要：以熔喷聚丙烯(PP)非织造布为基材,利用低温等离子体改性技术,在PP非织造布表面上引入甲基丙烯酸丁酯(BMA)单体,制备了PP-g-BMA吸油材料。分析了等离子体处理功率、压强、时间对接枝率的影响规律,并考察了液相接枝制备聚丙烯吸油材料的最佳工艺条件。采用傅里叶变换红外光谱(FT-IR)表征材料表层化学结构的变化。结果表明,在最适反应条件下,接枝率为7.2%,对甲苯的饱和吸附率为13.8g/g。PP-g-BMA was prepared with melt-blown polypropylene grafting polymerization of BMA by cold plasma.The influence of cold plasma modified conditions such as power,pressure and time on the grafting ratio were analyzed,while the best liquid grafting conditions were also investigated.Molecular structure of the PP surface was characterized by FT-IR.Under the best condition,the grafting ratio was 7.2% and the saturated adsorption of the PP-g-BMA to toluene was 13.8g/g.
