In this paper, a novel flexible nanogenerator (FNG) made of zinc-oxide (ZnO) nanoparticles (NPs) and multiwall-carbon nanotubes (MW-CNTs) is presented. In this structure, ZnO NPs and MW-CNTs are mixed with polydimethylsiloxane (PDMS) uniformly to form an entire flexible nanogenerator. Serial tests illustrate that the output voltage and power density are as high as 7.5 V and 18.75 μW per cycle, respectively. Furthermore, by foot stamp on the FNG, a peak voltage as high as 30 V can be generated. Comparing to the control samples, it is also proved that adding MW-CNTs into the matrix could significantly enhance the output voltage from 0.8 to 7.5 V. In summary, our work indicates that the realization of flexible nanogenerators made of ZnO NPs and MW-CNTs is technologically feasible, which may bring out some important and interesting applications in energy harvesting.
本文提出了一种由氧化锌（ZnO）纳米粒子（NPs）和多壁碳纳米管（MW-CNTs）组成的新型柔性纳米发电机（FNG）。在这种结构中，ZnO NPs 和 MW-CNTs 与聚二甲基硅氧烷（PDMS）均匀混合，形成完整的柔性纳米发电机。串联测试表明，输出电压和功率密度分别高达 7.5 V 和 18.75 μW 每周期。此外，通过在 FNG 上踩踏，可以产生高达 30 V 的峰值电压。与对照样品相比，还证明了在基质中添加 MW-CNTs 可以显著提高输出电压，从 0.8 V 提高到 7.5 V。总之，我们的工作表明，由 ZnO NPs 和 MW-CNTs 制成的柔性纳米发电机的实现在技术上是可行的，这可能为能量收集带来一些重要而有趣的应用。
