具有高输出性能的柔性压电纳米发电机（PENGs）是一种非常理想的能量收集材料。将摩擦纳米发电机（TENGs）与摩擦纳米发电机（peng）耦合是一种提高输出性能的可行方法，但其复杂的结构和熟练的操作要求限制了杂交纳米发电机的发展。在这项工作中，使用再生纤维素/BaTiO3 （C/BT）气凝胶纸为基础的聚二甲基硅氧烷（PDMS）纳米复合材料开发了柔性高性能peng。得益于四边形BT纳米颗粒的高负载和均匀分散，以及纳米复合材料的杨氏模量的增强，在外部机械冲击下，peng可以表现出15.5 V的最大电压和11.8 mu W的最大功率。通过引入单电极TENG，设计和制备了一种创新的混合纳米发电机，将不同的机械能收集技术结合在一个装置中。正耦合效应可以有效地将杂化纳米发电机的输出电压和功率分别提高到48 V和85 mu W。本研究为设计和制备结构简单、灵活性高、操作方便的高输出杂化纳米发电机提供了新的思路。
Flexible piezoelectric nanogenerators (PENGs) with high output performance are highly desirable for energy harvesting. Coupling triboelectric nanogenerators (TENGs) with the PENGs is a feasible method to enhance the output performance, while the complicated structure and the requirement of skillful operation limited the development of hybridized nanogenerators. In this work, flexible high-performance PENGs are developed using regenerated cellulose/BaTiO3 (C/BT) aerogel papers based polydimethylsiloxane (PDMS) nanocomposites. Benefiting from the high loading but uniform dispersion of tetragonal BT nanoparticles and the enhanced Young Modulus of the nanocomposites, the PENGs can exhibit a maximum voltage of 15.5 V and a maximum power of 11.8 mu W under an external mechanical impact. By introducing a single electrode TENG, an innovative hybridized nanogenerator has been designed and prepared, which combine different mechanical energy harvesting techniques in a single device. Polarized along proper direction of the PENG, the positive coupling effect can efficiently increase the output voltage and power of the hybridized nanogenerator to 48 V and 85 mu W, respectively. This research offers new insights into the design and preparation of high output hybridized nanogenerator with simple structure, high flexibility and easy operation.
