Abstract

Nitride salts were added to polyvinylidene fluoride fibers and then the fiber mats were prepared by electrospinning. An experimental investigation of the structure was provided by Raman, FTIR, SEM, and XRD. The phase ratio of the polymer was studied both theoretically and experimentally in connection with the addition of the hydrates Mg(NO), Ca(NO), and Zn(NO) salts. The comparison of simulated and experimental data for vibrational spectroscopies is discussed. We provide a comparison of triboelectric, dielectric, and compositional characterization of PVDF fibers doped with three types of nitride hydrates. Doping of PVDF fibers with magnesium nitrate hexahydrate leads to significant improvement of the triboelectric performance.

摘要

将氮化物盐添加到聚偏氟乙烯纤维中，然后通过静电纺丝制备纤维毡。通过拉曼光谱、傅里叶变换红外光谱、扫描电子显微镜和X射线衍射对结构进行了实验研究。结合添加水合物Mg(NO)、Ca(NO)和Zn(NO)盐，从理论和实验两方面研究了聚合物的相比例。讨论了振动光谱模拟数据与实验数据的比较。我们对掺杂三种氮化物水合物的聚偏氟乙烯纤维的摩擦电、介电和成分表征进行了比较。用六水合硝酸镁掺杂聚偏氟乙烯纤维可显著提高其摩擦电性能。
