摘  要:采用常压等离子体设备,以空气为介质对聚丙烯(PP)熔喷非织造布进行处理,并在15%的丙烯酰胺水溶液中进行接枝聚合。表面衰减全反射红外光谱(ATR-FTIR)分析的结果表明,等离子体处理后,非织造布已接枝上聚丙烯酰胺(PAM)。经接枝改性的样品,亲水性得到持久提高,接触角由处理前的135°降低至110°,放置后接触角不变。未经接枝PAM的样品,放置后接触角回复至130°。扫描电镜观察的结果表明,等离子体处理对PP纤维产生明显的刻蚀,接枝后的PP纤维表面有突出物。Polypropylene (PP) melt-blown nonwoven fabric was treated by atmospheric-pressure air plasma, and subsequently the sample was grafted using acrylamide as monomer in 15% acrylamide water solution. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FFIR) confirmed the grafting of polyacrylamide (PAM) onto the surface of the nonwoven sample. Grafting with PAM made the plasma-treated sample durably hydrophilic, its contact angle decreased from 135°( original sample ) to 110° and remained unchanged after storage, while the contact angle of untreated sample reverted to 130°. Scanning electron microscopy indicated that plasma treatment had significantly etched the surface of PP fiber and there were projections on the fiber of grafted-sample.
