Type: article
Abstract: MnO 2 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 2 nanowires (MnO 2 NW), likely due to cationic charge transfer from the tribopositive CMP layers to the surface Mn 2+ and Mn 3+ species of MnO 2 NW. This is supported by model studies. The MnO 2 @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 −2 . Spring‐assisted triboelectric nanogenerators fabricated with MnO 2 @CMP‐2/PVP‐3 films are used as power supplies to operate electronic devices.
