摘要：

为提高聚丙烯腈(PAN)纤维膜的压电性能,将硝酸钠(NaNO3)掺杂到PAN中,利用静电纺丝技术制备了PAN/NaNO3纳米纤维膜。探究了NaNO3用量以及纺丝速度对静电纺PAN纤维膜压电性能的影响。通过扫描电子显微镜、红外光谱仪、X射线衍射仪、驻极体非织造压电性能测试系统以及压电测试仪对PAN/NaNO3纤维膜的表面形貌、构象和压电性能进行表征与测试。结果表明:将NaNO3掺杂到PAN中会导致纤维膜的平面锯齿构象含量增加,晶面间距减小,进而影响PAN纤维膜的压电性能;当NaNO3质量分数为0.9%、纺丝速度为1 000 mm/s时,纤维膜的压电性能明显提高,此时PAN/NaNO3纤维膜中平面锯齿构象含量最多,晶面间距最小,与未掺杂NaNO3的PAN纤维膜相比,此PAN纤维膜压电电压和电流分别提高了40%和174.53%。

Abstract:

In order to improve the piezoelectric properties of polyacrylonitrile (PAN) fiber membranes, sodium nitrate (NaNO3) was doped into PAN, and PAN/NaNO3 fiber membranes were prepared by electrospinning. The effects of NaNO3 content and spinning speed on piezoelectric properties of the electrospun PAN fiber membranes were investigated. The surface morphology, conformation and piezoelectric properties of PAN/NaNO3 fiber membranes were characterized by scanning electron microscopy, infrared spectroscopy, X-ray diffraction, electret nonwoven piezoelectric performance testing system and piezoelectric tester. The results show that doping NaNO3 into PAN can increase the planar zigzag conformation content and decrease the crystal plane spacing, thus affecting the piezoelectric properties of PAN fiber membranes. In particular, when the doping amount of NaNO3 is 0.9% and the spinning speed is 1 000 mm/s, the piezoelectric properties of fiber membranes are improved notably. At the same time, the planar sawtooth conformation content of PAN/NaNO3 fiber membrane is the highest and crystal plane spacing is the smallest. The piezoelectric voltage and current of this PAN fiber membrane are increased by 40% and 174.53% respectively.

Key words: sodium nitrate, polyacrylonitrile fiber membrane, nanofiber membrane, electrospinning, piezoelectric property
