静电纺丝是制备纳米纤维简便而有效的方法，然而由传统平板收集的纤维网中纤维不能形成有序的排列，并且孔隙较小，影响其应用。采用带有冲孔的金属滚筒作为接收装置收集静电纺聚己内酯纤维。试验表明：纤维收集1h时，纤维网能在接收装置冲孔处形成圆孔形状，随着收集纤维的增多，圆孔形状逐渐模糊，4 h时基本消失。电镜图片显示，在纺丝1 h时，纤维网中纤维有两种密度的排列，圆孔处密度小（即形成大孔），周围密度大；并且，纤维的取向排列也不同，在圆孔处纤维的取向度高，而在周围取向度低。

Electrospun is a simple and effective method to continuously prepare nanofibers.However, the nanofibers in fiber sheet can’t keep regular arrangement and the pores are usually small, which affect their application in tissue engineering.In this paper, the collector of electrospun, made from metal cylinder with punching hole, was used to collect polycaprolactone fibers.The results show that the fiber sheet forms in the shape of a circular around the punching hole after 1 processing hour and disappears after 4 hours.The SEM images show that there are two different distributions of nanofibers in fiber sheet after 1 processing hour, the low density at the punching hole and the high density around.Moreover, the arrangement of nanofibers is also different, regular at punching hole and irregular around.
