羊毛角蛋白/聚丙烯腈电纺膜的制备及性能

摘要

Wool keratin was prepared by using reduction to dissolve wool, and blending wool keratin solution and polyacry-lonitrile solution to spin film, which can improve hydrophilic of polyacrylonitrile film. The blend fiber film surface morphology and structure were observed and analyzed by environmental scanning electron microscope (ESEM) and Fourier transform infrared spectroscopy (FT-IR), the effects of the addition of wool keratin on fiber film per-formance were observed. The results indicated that adding right amount of wool keratin to the polyacrylonitrile has small effects on the mechanical properties of the electrospinning film, wool keratin contains large amounts of hy-droxyl, amino, so the addition of the wool keratin improves greatly the hygroscopic of polyacrylonitrile fiber film. When the content of wool keratin is 27%,the wool keretin/polyacrylonitrile electrostatic spinning film has good mechanical properties and hydrophilic.%利用还原法溶解羊毛制备羊毛角蛋白,采用羊毛角蛋白溶液与聚丙烯腈溶液共混电纺成膜,改善聚丙烯腈电纺膜的亲水性.利用环境扫描电子显微镜(ESEM)、傅里叶变换红外光谱(FT-IR)对共混电纺膜表面形貌和结构进行观察和分析,考察了羊毛角蛋白的加入对电纺膜性能的影响.结果表明:羊毛角蛋白的适量加入对聚丙烯腈电纺膜的力学性能影响不大,但是羊毛角蛋白中含有大量的羟基、氨基等亲水性基团,大大提高了聚丙烯腈电纺膜的吸水性;当羊毛角蛋白质量分数为27%时,羊毛角蛋白/聚丙烯腈电纺膜的力学性能和亲水性能均优.
