摘要

摘要:线性阵列针头近场直写是一种高效制备大面积微纳结构的电流体动力喷印技术，如何控制带电多射流在多物理场耦合情况下准确及高密度沉积是关键。为了有效研究线性阵列针头近场直写有序纤维过程中各参数对纤维沉积间距的影响，采用正交试验设计法，发现了针长、针间距、电压及极距对纤维沉积间距的交互作用及敏感度，并研究了阵列多针下各参数对纤维沉积间距的影响作用。最后提出并验证了旋转阵列针头来提高纤维密度的方法，实验结果对未来高效准确直写微纳结构具有一定指导作用。

Abstract

Nearfield electrospinning (NFES) directwriting of linear multinozzleis a highly efficient electrohydrodynamic technique for massvolume fabricatingmicronano structures. To control charged jets todeposit aligned nanofibers accurate and denser with multiphysical couplingduring linear multinozzle NFES process was crucial concern. In order to study theinfluence of electrospinning parameters on deposition distance of alignednanofibers during linear multinozzle NFES. With orthogonal experimental design

the influenceand sensitivity of needle length

needle spacing and applied voltage ondeposition distance is investigated.Moreover

the method of improving density of aligned nanofibers by rotatingmultinozzle setup is proposed and proved. This study can be greatly contributed to guide todirectwrite micro/nano structures in highefficient and accurate way.
