rmation of Thermoplastic Polyuretha

rmation of Thermoplastic Polyurethane (TPU) Nano/Micro Fibers by Electrospinning Process Using Electrode with Tines.
Electrospinning is a process during which polymer fibers with a diameter in nano and micro range due to the action of an external electric field effected on a polymer solution or melt are produced. The aim of this study is to form thermoplastic polyurethane (TPU) mats by electrospinning process. TPU solutions of 3 wt.% and 4 wt.% concentrations were prepared for the experiments. It was not possible during the tests to create any TPU fibers using plain cylindrical electrode, so two types of electrodes with tines were used in this study. TPU mats from microfibers, nanofibers and stick nanofibers were formed by electrospinning process at different applied voltage and solution concentrations. It was determined that the type of electrode has influence only on the structure of the electrospun TPU mats, but not on the diameter of formed fibers.

热塑性聚氨酯 (TPU) 纳米/微米纤维的纺丝过程使用电极尖叉的构建。静电纺丝技术是生产过程期间的聚合物纤维直径在外电场作用下的纳米技术和微观范围内影响聚合物溶液或熔体。本研究的目的是，通过静电纺丝过程形成热塑性聚氨酯 (TPU) 垫。TPU 解决方案 3 wt.%和 4 wt.%浓度已准备实验。在执行测试时创建任何使用普通圆柱电极，因此在本研究中采用两种类型的电极与尖叉的 TPU 纤维不是可能的。TPU 席子从超细纤维、 纳米纤维和纳米纤维棒形成了静电纺丝过程在不同电压、 溶液浓度。它是已确定的电极类型有只对结构的电纺 TPU 垫，但不是形成的纤维直径的影响。

热塑性聚氨酯（TPU）的微/纳米静电纺丝过程中使用的电极尖端的纤维。
静电纺丝是一种过程，聚合物纤维的直径在纳米和微观范围由于行动的外部电场影响聚合物溶液或熔体的产生。本研究的目的是形成热塑性聚氨酯（TPU）通过静电纺丝过程中垫。制备实验TPU解3重量%和4重量%的浓度。这是不可能用普通圆柱电极产生任何TPU纤维测试期间，所以两种电极叉进行了研究。TPU垫超细纤维，在不同外加电压和溶液浓度下，用电纺丝法制备纳米纤维和纳米纤维。确定了电极的类型只对静电TPU膜的结构有影响，但不会对形成的纤维的直径。
