近场静电纺丝（NFES）工艺已经被开发用于以直接、连续和可控的方式沉积存款固体纳米纤维。使用尖端直径为25 μ m的钨电极在硅基收集器上构建线宽为50-500 nm的纳米纤维，同时以类似于蘸液笔的方式供应液体聚合物溶液。最小施加偏压为600 V，最小电极-集电极距离为500 μ m，以实现位置可控沉积。带电的纳米纤维可以有序地收集，使NFES成为用于各种材料的直写纳米纤维的潜在工具。
A near-field electrospinning (NFES) process has been developed to deposit solid nanofibers in a direct, continuous, and controllable manner. A tungsten electrode with tip diameter of 25 ym is used to construct nanofibers of 50-500 nm line width on silicon-based collectors while the liquid polymer solution is supplied in a manner analogous to that of a dip pen. The minimum applied bias voltage is 600 V, and minimum electrode-to-collector distance is 500 mu m to achieve position controllable deposition. Charged nanofibers can be orderly collected, making NFES a potential tool in direct write nanofabrication for a variety of materials.
