Abstract

This study aimed to develop a novel hybrid piezoelectric structure based on poly(vinylidene difluoride) nanofibers (PVDF NFs) and zinc oxide nanorods (ZnO NRs) which eliminate the need for post poling treatment in such hybrid structures. Mechanism of electrical performance enhancement of the hybrid structure is also discussed in this paper. To study the effect of hybridization on piezoelectric performance, pristine ZnO NRs and pristine PVDF NF nanogenerators were also fabricated. The piezoelectric performance of these three nanogenerators was evaluated under periodic deformation at low frequency. The output power of the hybrid structure was found to be enhanced compared to pristine ZnO NRs and PVDF NFs nanogenerators. Such simple hybrid devices that do not need to complicated post poling treatment are more efficient than previous hybrid PVDF/ZnO nanogenerators for practical application. This improved piezoelectric nanogenerator is expected to enable various applications in the field of self-powered devices and wearable energy harvesting to harvest mechanical energy from the human activities.

摘要

本研究旨在开发一种基于聚偏氟乙烯纳米纤维（PVDF NFs）和氧化锌纳米棒（ZnO NRs）的新型混合压电结构，该结构无需对这种混合结构进行后极化处理。本文还讨论了混合结构电性能增强的机制。为了研究杂交对压电性能的影响，还制备了原始的ZnO NRs和原始的PVDF NF纳米发电机。在低频周期性变形下评估了这三种纳米发电机的压电性能。结果发现，与原始的ZnO NRs和PVDF NFs纳米发电机相比，混合结构的输出功率有所提高。这种无需复杂后极化处理的简单混合器件在实际应用中比以前的混合PVDF/ZnO纳米发电机更高效。这种改进的压电纳米发电机有望在自供电设备和可穿戴能量收集领域实现各种应用，以从人类活动中收集机械能。
