聚合物纤维的制备是通过静电纺丝法，利用在毛细管中的铜线电极。静电纺丝聚乙烯醇（PVA）纤维的形态进行了观察，并被发现是依赖于线电极在毛细管中的尖端位置，聚合物溶液的浓度，电极之间的距离，和所施加的电压。采用线电极，实验装置简单，电极间距和外加电压可以很容易地减小。在此基础上，制备了聚3-己基噻吩（P3 HT）纤维。通过将聚氧化乙烯（PEO）与P3 HT溶液共混，成功地制备了P3 HT纤维。取向控制也通过将纤维沉积在旋转集电极上来进行，并且确认了P3 HT：PEO纤维的对齐。光学吸收光谱的各向异性也观察到的对齐的光纤。
Polymer fibers were prepared by an electrospinning method utilizing a copper wire electrode in a capillary tube. The morphology of electrospun poly(vinyl alcohol) (PVA) fibers was observed, and was found to be dependent on the wire electrode tip position in the capillary tube, the concentration of the polymer solution, the distance between the electrodes, and the applied voltage. By using the wire electrode, the experimental setup is simple and the distance between the electrodes and the applied voltage can be easily reduced. Furthermore, the preparation of poly(3-hexylthiophene) (P3HT) fibers was carried out. P3HT fibers were successfully prepared by mixing poly(ethylene oxide) (PEO) in P3HT solution. Orientation control was also carried out by depositing the fibers on a rotating collector electrode, and the alignment of the P3HT:PEO fibers was confirmed. Anisotropy of the optical absorption spectra was also observed for the aligned fibers.
