Polymer solutions with different concentrations of SU-8 2002/poly(ethylene) glycol/tetrabutyl ammonium tetrafluoroborate (SU-8/PEO/TBATFB) were electrospun in a low-voltage near-field electrospinning platform (LVNFES) at different velocities. Their diameters were related to the concentration contents as well as to their Deborah () numbers, which describes the elasticity of the polymer solution under determined operating conditions. We found a direct correlation between the concentration of PEO/TBATFB, the and the diameter of the fibers. Fibers with diameters as thin as 465 nm can be achieved for ≈ 1.
在低电压近场静电纺丝平台（LVNFES）上，以不同速度对含有不同浓度SU-8 2002/聚乙二醇/四丁基四氟硼酸铵（SU-8/PEO/TBATFB）的聚合物溶液进行静电纺丝。其直径与浓度含量以及德博拉（De）数有关，德博拉数描述了在特定操作条件下聚合物溶液的弹性。我们发现PEO/TBATFB的浓度、De数与纤维直径之间存在直接关联。对于De≈1的情况，可以制备出直径低至465 nm的纤维。
