MnO<sub>2</sub> Nanowires with Sub‐10 nm Thick Conjugated Microporous Polymers as Synergistic Triboelectric Materials
MnO<sub>2</sub> 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<sub>2</sub> nanowires (MnO<sub>2</sub> NW), likely due to cationic charge transfer from the tribopositive CMP layers to the surface Mn<sup>2+</sup> and Mn<sup>3+</sup> species of MnO<sub>2</sub> NW. This is supported by model studies. The MnO<sub>2</sub>@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<sup>-2</sup>. Spring-assisted triboelectric nanogenerators fabricated with MnO<sub>2</sub>@CMP-2/PVP-3 films are used as power supplies to operate electronic devices.
