以不同浓度尼龙6/甲酸溶液通过静电纺丝制得的纳米纤维毡为研究对象,确立了溶液性质、电场以及喷丝头到收集装置的距离对纤维匀度、形态和平均直径的影响。研究发现,纺制均匀尼龙6纤维的最佳聚合物溶液浓度为20wt%、电压15kV、纺丝距离8cm。描述了能够生产悬浮于两个接地圆盘之间的束状纤维的简单技术。在与电源正极相连的喷丝头和接地圆盘之间的静电场力作用下,纤维定向排列并被拉伸。改变圆盘间距离和收集时间以系统地研究尼龙6纤维的排列和密度。通过改变收集时间、电压和圆盘间距离,可以控制纤维束里的纤维根数。扫描电镜图片显示,随着圆盘间距离和收集时间的增加,纤维的定向排列程度提高。还全面回顾了使纳米纤维整齐排列的不同装置的设计。
The effects of solution properties, electric field, and the distance between the spinneret and the collection device on the fiber formation, morphology and average diameter were investigated using nanofibers prepared by electrospinning nylon 6 / formic acid solutions at different concentrations. The study found that the optimum concentration of the polymer solution of spinning uniform nylon 6 fiber 20wt%, voltage 15kV, spinning distance 8cm. Describes a simple technique capable of producing bundle-like fibers suspended between two grounded disks. Under electrostatic field forces between the spinneret connected to the positive pole of the power source and the grounding disc, the fibers are oriented and stretched. The interdisc distance and collection time were varied to systematically investigate the arrangement and density of nylon 6 fibers. By changing the collection time, the voltage and the distance between the discs, the number of fibers in the bundle can be controlled. Scanning electron micrographs showed that the degree of orientation of the fibers increased as the distance between discs and the collection time increased. A comprehensive review of the design of the different devices that neatly arrange the nanofibers is also given.
