摘　　要：纳米纤维薄膜因其特殊的构成和易于调控的表面结构而成为疏水改性的研究热点。静电纺丝技术制备纳米纤维具有成本低廉、工艺简单的特点而被广泛应用。通过静电纺丝技术将适当比例的醋酸纤维素(CA)和聚丙烯腈(PAN)进行物理混纺,获得了一种结构和性能都优异的复合纳米纤维薄膜。结果表明:CA/PAN纳米纤维薄膜的最大水接触角为122°,最大吸油系数为8.93g/g,且具有超高的水粘附性。Nanofiber films have become a hot research topic in hydrophobic modification because of their special composition and easily controlled surface structure.Electrospinning technology for nanofiber preparation is widely used due to its low cost and simple process.In this paper,a composite nanofiber film with excellent structure and properties was obtained by electrospinning technique through physically blending appropriate proportions of CA and PAN.The results showed that the maximum water contact angle of CA/PAN nanofiber film was 122°,the maximum oil absorption coefficient was 8.93g/g,and the film had super-high water adhesion.
