We report on the electrospinning of poly(vinylidene fluoride-hexafluoropropylene) [P(VDF-HFP)] nanofibers doped with silver nanoparticles for the preparation of a polymer based nanogenerator (PNG). It has been found that the yield of the piezoelectric phase is increased by the addition of silver nanoparticles. Furthermore, defects in the P(VDF-HFP) electrospun fibers are removed resulting in a significant enhancement in the output power of the PNG. A maximum generated PNG output voltage of 3 V with a current density of 0.9 μA cm(-2) is achieved.
我们报道了用于制备聚合物基纳米发电机（PNG）的掺杂银纳米颗粒的聚（偏二氟乙烯-六氟丙烯）[P（VDF-HFP）]纳米纤维的静电纺丝。已发现添加银纳米颗粒可提高压电相的产率。此外，P（VDF-HFP）静电纺丝纤维中的缺陷被消除，从而使PNG的输出功率显著提高。实现了PNG的最大输出电压为3 V，电流密度为0.9 μA cm(-2)。
