摘要(Abstract)：

为获得高性能压电纳米发电机，提出了在纳米纤维基压电纳米发电机中构筑导电通路的策略，以提高其电荷传输能力。首先，通过静电纺丝技术和煅烧工艺制备钛酸钡（BaTiO_3）纳米纤维，并研究纺丝条件和煅烧工艺对其形貌和结构的影响；其次，通过物理浸泡的方式掺杂不同浓度的多壁碳纳米管（MWCNT），与聚二甲基硅氧烷（PDMS）复合获得柔性压电纳米发电机，探讨MWCNT的含量对压电纳米发电机输出性能的影响。结果表明：纺丝液质量分数为42%、挤出速率为1 mL/h、煅烧温度为1 000℃、升温速率为2℃/min时，获得形貌结构和结晶性良好的BaTiO_3纳米纤维膜；MWCNT质量分数为3%时，压电纳米发电机的综合性能最佳，开路电压和短路电流分别高达23 V和2.6μA，较纯BaTiO_3基压电纳米发电机性能提高4倍。本研究为设计和制备高性能压电纳米发电机提供了新的思路。
