Abstract Various aspects of electrospun fibers prepared from terpolymer of tetrafluoroethylene (TFE), hexafluoropropylene (HFP), and vinylidene fluoride (VDF) (THV)/acetone solutions at two applied voltages, THV/acetone solutions having Texas montmorillonite with two ratios, and THV/ethyl acetate solutions using two needle sizes are described. Fibers from THV/acetone and THV/ethyl acetate solutions showed shallow indentations and pores, respectively. The clay, functioning as electrospinning agent, did not influence the fiber morphology, but yielded narrower fiber diameter distribution and the thinnest fibers. Heterogeneous fiber diameter distribution and increase in the fiber diameters were observed by lowering the voltage for fibers of THV/acetone solutions. Fibers from THV/ethyl acetate solutions had the largest diameter and the broadest diameter distribution. Electrospun THV fibers having both hydrophobic characteristics with nearly 140° water contact angles and oleophilic properties with oil contact angles less than 45° might have applications in areas such as water/oil separation.

含氟三元共聚物纤维薄膜的润湿行为

摘要 由四氟乙烯 (TFE)、六氟丙烯 (HFP) 和偏二氟乙烯 (VDF) (THV)/丙酮溶液在两种施加电压下制备的电纺纤维的各个方面，具有两种比例的德克萨斯蒙脱石的 THV/丙酮溶液和 THV描述了使用两种针头尺寸的乙酸乙酯溶液。来自 THV/丙酮和 THV/乙酸乙酯溶液的纤维分别显示出浅凹痕和孔隙。用作静电纺丝剂的粘土不影响纤维形态，但产生更窄的纤维直径分布和最细的纤维。通过降低 THV/丙酮溶液纤维的电压，观察到不均匀的纤维直径分布和纤维直径的增加。来自 THV/乙酸乙酯溶液的纤维具有最大的直径和最宽的直径分布。具有接近 140° 水接触角的疏水特性和具有小于 45° 油接触角的亲油特性的电纺 THV 纤维可能在水/油分离等领域得到应用。
