借助静电纺工艺,可以获得定向排列纤维,这些纤维具有细胞培养的培养基、组织工程支架、补强材料以及电子材料等较多的潜在用途.利用一种简单的接收装置同时获得了8组定向排列的静电纺纳米纤维阵列,这种接收装置是由8根交于中心的不锈钢棒组成.通过光学显微镜以及电镜观察可以发现,沿单轴定向排列的亚微米纤维横跨于两根临近不锈钢棒中间,整体外观与蜘蛛网相似.研究了电压和接收时间对纤维定向排列的影响,结果发现,随着电压的增加,定向排列的纤维长度会增加,而且,随着收集时间的增加,定向排列纤维产量和纤维的定向排列程度都会增加.实验结果表明,这种方法不仅简单、价廉而且产量高,同时还可以赋予纤维阵列较高的定向排列程度.
With the electrospinning process, oriented fibers can be obtained that have many potential uses for cell culture media, tissue engineering scaffolds, reinforcing materials, and electronic materials, etc. With a simple receiver, 8 sets of orientations Arrangement of the electrospun nanofiber array, this receiving device is composed of eight intersecting centers of the stainless steel rod composition by optical microscopy and electron microscopy can be found along the uniaxial orientation of submicron fibers across two adjacent stainless steel rod In the middle, the overall appearance is similar to that of cobwebs.The effect of voltage and time on the fiber orientation was investigated and it was found that the length of the aligned fibers increases with increasing voltage, and as the collection time increases, Fiber yield and fiber orientation will increase.Experimental results show that this method not only has the advantages of simple, inexpensive and high yield, but also can give higher orientation of the fiber array.
