摘要:

以制备的银负载氧化锌纳米棒(Ag/ZnO NRs)为填料, 通过非溶剂诱导相转化法(NIPS)构筑了具有 均匀多孔结构的Ag/ZnO⁃P(VDF-TrFE)复合压电薄膜. 研究发现, NIPS法能够诱导聚偏二氟乙烯-三氟乙 烯[P(VDF-TrFE)]形成高含量的极性β相压电活性晶区; 同时, Ag/ZnO异质结诱导极化电荷单向流动并放大微观电压. 所制备的压电纳米发电机展现出优异的压电输出和力敏特性, 满足将生物机械能高效转化为电能的需求. 本研究为高性能自极化压电纳米发电机的发展提供了一种简单且可扩展的策略.

Abstract:

A Ag/ZnO⁃P(VDF-TrFE) composite piezoelectric film with a uniform porous structure was constructed via non-solvent induced phase separation(NIPS) with silver-loaded zinc oxide nanorods(Ag/ZnO NRs) as fillers. It was found that the NIPS method induces the formation of high-content polar β-phase piezoelectric active crystalline regions in P(VDF-TrFE). Meanwhile, the Ag/ZnO heterojunction induces unidirectional migration of polarization charges and amplifies the microscale voltage. The as-fabricated piezoelectric nanogenerator exhibits excellent piezoelectric output and force-sensitive characteristics, meeting the demand for efficient conversion of biomechanical energy into electricity. This work provides a simple and scalable strategy for the development of high-performance self-polarized piezoelectric nanogenerators.
