The polyurethane nanofibres have been prepared by electrospinning and the effects of different types of acids, bases, and salts on nanofibre diameters within the polyurethane solutions are studied. Nanofibre diameters are measured with the SEM and the changes in nanofibre morphology are investigated by considering the electrical conductivity, viscosity, and surface tensions of dopants. Deterioration is observed in the nanofibre morphology in the presence of acid, whereas the nanofibres obtained in the presence of salt are found smoother, longer and thinner. Homogeneous, fine and smooth nanofibres are obtained from salt-doped polyurethane solutions.

某些酸，碱和盐对聚氨酯纳米纤维形态的影响

聚氨酯纳米纤维是通过静电纺丝制备的，研究了不同类型的酸，碱和盐对聚氨酯溶液中纳米纤维直径的影响。用SEM测量纳米纤维直径，并通过考虑掺杂剂的电导率，粘度和表面张力来研究纳米纤维形态的变化。在存在酸的情况下，在纳米纤维形态中观察到了劣化，而发现在存在盐的情况下，所获得的纳米纤维更光滑，更长，更细。从掺杂盐的聚氨酯溶液中可获得均质，细腻且光滑的纳米纤维。
