制备了石墨烯增强聚偏氟乙烯复合纳米纤维，并首次对其形貌、结晶度、多态性和电输出进行了研究。采用静电纺丝技术制备了不同石墨烯含量的纳米纤维。用DSC、FTIR和WAXD分析了加入石墨烯后PVDF晶体的多态性。结果表明，少量石墨烯（0.1%wt）的加入显著提高了纳米纤维的F（β）和开路电压。然而，石墨烯含量的进一步增加会降低随机取向纳米纤维的电输出。开发的PVDF/石墨烯纳米发电机具有完全同步手指运动的能力，其产生的电力可以点亮商用LED 30秒。这种新型PVDF发电机有可能被用作自充电电源，并可用于为个人电子产品供电。(C) 2016 Elsevier Ltd.版权所有。
Graphene reinforced Poly(vinylidene fluoride) composite nanofibers were prepared and their morphology, crystallinity, polymorphism and electrical outputs were investigated for the first time. Nanofibers were prepared using electrospinning technique with different graphene contents. DSC, FTIR and WAXD analyses were used to evaluate the polymorphism of PVDF crystals upon graphene addition. It was observed that addition of a small amount of graphene (0.1%wt) significantly increased the F(beta) and open-circuit voltage of nanofibers. However, further increase in graphene content decreased the electrical output of randomly oriented nanofibers. The developed PVDF/graphene nanogenerator has the ability to fully synchronize the finger movement and its generated electricity can light up a commercial LED for 30 s. This new type of PVDF generator has the potential to be used as a self-charging power source and could be used in powering the personal electronics. (C) 2016 Elsevier Ltd. All rights reserved.
