摘要(Abstract)：

采用静电纺丝技术,以特殊设计的金属丝螺旋盘绕滚筒作为接收装置,制备了具有一定取向的丝素蛋白(SF)-聚乙烯醇(PVA)共混纳米纤维材料。利用扫描电子显微镜(SEM)对纤维形貌进行观察,并通过Image-Pro Plus软件对纤维细度进行测试,探讨了SF与PVA的配比以及纺丝电压、接收距离等静电纺丝参数对所得纳米纤维形貌、细度及其分布的影响。结果表明:将质量浓度为25 kg/L的SF与质量分数为8%的PVA以质量比15∶3.2共混,并采用20 kV的纺丝电压和13 cm的接收距离静电纺时,所得纳米纤维的平均直径约为238 nm,且直径分布较为均匀。采用该法制得的纳米纤维材料具有一定的纤维取向,有利于细胞生长,可应用于生物医药领域。
The nanofiber materials having certain degree of orientations were prepared through electrospin-ning technology, with specially designed metallic spiral wound roller as fiber receiver, to obtain nanofibersbased on the blend of silk fibroin(SF) and polyvinyl alcohol(PVA), which are expected to have extensive ap-plications in biomedical fields. The impact on the resultant nanofiber morphology, fiber diameter and its dis-tribution from parameters such as ratio of SF/PVA, spinning voltage, receiving distance and so on, were dis-cussed in this study, via fiber morphology observation using SEM and the fiber diameter measurement usingImage-ProPlussoftware.Theresultsindicatedthattheaverageddiameterofresultingnanofiberswas 238 nmwith uniform diameter distribution, when the electrospinning was performed by blending 25 kg/L SF with8 % PVA at the mass ratio of 15.0∶3.2, and the spinning voltage of 20 kV, the fiber receiving distance of13 cm. Furthermore, the nanofibers resulted from this method were oriented to some degree, favoring thecell growth and could be applied in the field of biomedicine.
