连续供液的旋转电极式无针尖静电纺丝采用圆柱滚筒电极代替喷丝头实现了高产量纳米纤维制造.该方法避免了喷丝头的堵塞问题,同时也实现了纳米纤维的连续生产.本文利用扫描电镜(SEM)探讨了该制作过程中的关键参数,如溶液浓度、偏置电压、旋转速度以及溶液厚度等对纳米纤维直径的影响.实验结果表明,纳米纤维的平均直径随溶液浓度、圆柱滚筒电极旋转速度和溶液厚度的增大而增大,但随着偏置电压、圆柱滚筒电极直径的增大而减小.圆柱滚筒电极长度为12 cm、直径为60 mm时制备的纳米纤维产量高达8.7 g/h,且纳米纤维的直径均小于500 nm.
Continuous Electroless Electrodeless Rotating Electrodeless Electrospinning Using Cylindrical Roller Instead of a Spinneret, High Yield Nano-Fibers Production Is Achieved This method avoids the plugging problem of the spinneret and also enables the continuous production of nanofibers. The key parameters such as solution concentration, bias voltage, rotation speed and solution thickness on the diameter of nanofibers were discussed by scanning electron microscope (SEM) .The experimental results show that the average diameter of nanofibers varies with the solution concentration, Cylindrical roller electrode rotation speed and the solution thickness increases, but with the bias voltage, cylindrical roller electrode diameter decreases.Drum cylindrical roller electrode length of 12 cm, the diameter of 60 mm when prepared nanofibers Yield up to 8.7 g / h, and the diameter of nanofibers are less than 500 nm.
