Study on formation mechanism of the Taylor cones at a melt-electrospinning process

为了从熔融电纺法中获得纳米纤维，我们研究了在不可渗透聚合物共混片表面形成的泰勒锥体形成纤维的机理。结果表明，纤维直径受泰勒锥顶端纤维形成的影响很大。考虑到这一结论，我们对激光熔融电纺设备进行了改进。结果表明，随着纺丝空间温度的升高，纤维直径明显减小。

In order to obtain nanofiber from melt electrospinning method, we investigate the fiber formation mechanism from the Taylor cones which are formed at the surface on the immisible polymer blend sheet. As a result, it is found that the fiber diameter is strongly influenced by the fiber formation which occurs at the tip of the Taylor cone. Taking account of this conclusion, we improve our laser meltelectrospinning apparatus. It is found that the fiber diameter is strongly reduced by increasing temperature of the spinning space.
