Abstract

MnO nanowires coated with conjugated microporous polymers (CMP) are applied as triboelectric energy harvesting materials. The tribopositive performance of the CMP shells is enhanced with the assistance of MnO nanowires (MnO NW), likely due to cationic charge transfer from the tribopositive CMP layers to the surface Mn and Mn species of MnO NW. This is supported by model studies. The MnO@CMP-2 with sub-10 nm thick CMP layers shows promising triboelectric output voltages up to 576 V and a maximum power density of 1.31 mW cm. Spring-assisted triboelectric nanogenerators fabricated with MnO@CMP-2/PVP-3 films are used as power supplies to operate electronic devices.

摘要

涂覆有共轭微孔聚合物（CMP）的MnO纳米线被用作摩擦电能量收集材料。在MnO纳米线（MnO NW）的辅助下，CMP壳层的摩擦正性能得到增强，这可能是由于阳离子电荷从摩擦正性的CMP层转移到MnO NW的表面Mn和Mn物种上。模型研究支持了这一点。具有亚10纳米厚CMP层的MnO@CMP-2显示出高达576 V的有前景的摩擦电输出电压和1.31 mW cm的最大功率密度。用MnO@CMP-2/PVP-3薄膜制造的弹簧辅助摩擦电纳米发电机被用作操作电子设备的电源。
