摘 要: 采用紫外(ultraviolet,UV)辐射引发的方法,在主要利用毛细管力作用吸油的聚丙烯(polypropylene, PP)纤维上接枝丙烯酸十二酯(lauryl acrylate,LA),制备了高吸油纤维。傅里叶红外光谱和扫描电子显微镜(scanning electron microscopy, SEM)测试结果表明:LA被成功接枝到PP纤维上。此外,研究了接枝率对吸油率和吸水率的影响,结果表明:随着接枝率的增大,吸油纤维对柴油的吸附量先增大后减小;当接枝率为20.55%时,对柴油的吸附倍率从原纤维的11.50 g/g提高到21.28 g/g. 同时,进一步研究了接枝LA的吸油纤维吸油机制。

Abstract: The surface of polypropylene (PP) fiber was modified through grafting polymerization of lauryl acrylate (LA) initiated by high energy ultraviolet (UV) in isopropanol/water mixture solution. The original and grafted PP fibers were characterized by Fourier transform infrared spectrometer and scanning electron microscopy (SEM), and the results indicated that LA was grafted onto the surface of PP fibers. With the increasing of grafting degree, the adsorption capacity of grafted fiber using diesel fuel as the adsorption capacity firstly increased and then decreased. When the grafting degree was 20.55%, the maximum oil-absorption capacity reached 21.28 g/g for diesel, while the oil-absorption capacity of PP fiber was only 11.50 g/g. The oil absorbing mechanism of the LA grafted PP fibers were also researched.
Key words: polymer chemistry; oil absorption mechanism; oil absorption resin; oil absorption fiber; graft
