Abstract
针尖诱导电纺技术(TIE)利用针尖阵列插入聚合物溶液表面后快速抽离,由于高压强电场和黏性力作用在液面抽离处诱导形成泰勒锥,进而在收集板上得到大量纳米纤维,实现纳米纤维的批量制造.实验结果表明在不同电极间距下,电纺阈值电压随着溶液浓度的增加而增大.当工作电压为63 kV,溶液槽尺寸为142 MMx50 MM时,电纺聚氧化乙烯(PEO)溶液的纤维产量达1.961 2 g/H.当工作电压从45 kV增加到63 kV时,纤维沉积均匀性变化范围为31.08%~43.23%.
 
Tip-induced electrospinning(TIE) is demonstrated to produce nanofibers with high throughput.Probe array was plunged into the plane polymer solution and then withdrawn quickly,and due to the effects of viscous force and the electric force,Taylor cones were generated from the position where the probes left,and then mass nanofibers were obtained on the collector.The experimental results show that the threshold voltage under different electrode distances increases with the increase of the concentration,and the mean throughput of polyethylene oxide(PEO) nanofibers is up to 1.961 2 g / h when the solution tank size is 142 mm × 50 mm and the applied voltage is 63 kV.And the maximum deposition error of nanofibers is within the range of 31.08% —43.23% on the condition that the applied voltage changes from 45 kV to 63 kV.
