Embedding additional ferroelectric dipoles in contacting polymer layers is known to enhance the performance of triboelectricnanogenerator (TENG) devices. However, the influence of dipoles formed between the triboelectric surface charges on two contacting ferroelectric films has been ignored in all relevant studies. We demonstrate that proper attention to the alignment of the distinct dipoles present between two contacting surfaces and in composite polymer/BaTiO₃ ferroelectric films can lead to up to four times higher energy and power density output compared with cases when dipole arrangement is mismatched. For example, TENG device based on PVAc/BaTiO₃ shows energy density increase from 32.4 μJ m⁻² to 132.9 μJ m⁻² when comparing devices with matched and mismatched dipoles. The presented strategy and understanding of resulting stronger electrostatic induction in the contacting layers enable the development of TENG devices with greatly enhanced properties.

已知在接触的聚合物层中嵌入其他铁电偶极子可增强摩擦电纳米发电机（TENG）装置的性能。但是，在所有相关研究中都忽略了摩擦表面电荷之间形成的偶极子对两个接触铁电薄膜的影响。我们证明，适当注意两个接触表面之间以及复合聚合物/ BaTiO ₃铁电薄膜中存在的不同偶极子的排列，与偶极子排列不匹配的情况相比，可导致高达四倍的能量和功率密度输出。例如，基于PVAc / BaTiO _3的TENG装置显示出能量密度从32.4μJm ^-2增加到132.9μJm ^-2比较具有匹配和不匹配偶极子的设备时。提出的策略和对在接触层中产生更强静电感应的理解，使TENG器件的性能大大提高。
