氧化石墨烯对丙纶非织造布抗静电改性研究

Study on antistatic modification of polypropylene nonwoven fabrics with graphene oxide

采用氧化石墨烯对丙纶非织造布进行抗静电改性。利用透射电子显微镜和扫描电子显微镜对氧化石墨烯和抗静电改性前后的丙纶非织造布的表面形态进行表征,并测试改性前后丙纶非织造布的抗静电性能及力学性能。结果表明:氧化石墨烯边缘带有褶皱结构;改性后丙纶非织造布纤维表面出现了沟槽和凹坑,氧化石墨烯附着在丙纶非织造布纤维表面;经氧化石墨烯改性的丙纶非织造布的抗静电性能和力学性能均得到较大的提高;且当氧化石墨烯的质量分数为1.2%时,改性后丙纶非织造布的综合性能达到最好。

Antistatic modification of polypropylene nonwoven fabrics was done through using gra- phene oxide＇ （GO）. The morphological properties of the graphene oxide and polypropylene nonwoven fabrics before and after modification were characterized by the transmission electron microscope and the scanning electron microscope respectively, and the antistatic performance and mechanical prop- erties of polypropylene nonwoven fabrics before and ＇after modification were tested. The results showed that, the edges of graphene oxide had folded structure. Fibers＇ surface of modified polypro- pylene nonwoven fabrics had grooves and pits, and graphene oxide attached to the fibers＇ surface of modified polypropylene nonwoven fabrics. The antistatic, performance and mechanical properties of polypropylene nonwoven fabrics modified with graphene oxide were improved greatly. When mass fraction of graphene oxide was at 1.2% , the combination properties of modified polypropylene non- woven fabrics reached the best.
