Abstract
Core-shell nanospheres were prepared by the homogeneous coating of piezoelectric ZnO nanorod aggregates with triboelectric microporous organic polymer (MOP). The small energy harvesting performance of ZnO@MOP was significantly enhanced, compared with those of ZnO and MOP, due to the piezoelectrification-induced polarization of inner ZnO and the enhanced generation of tribopositive charges of MOP. Piezo-triboelectric nanogenerators (PTENGs) fabricated with ZnO@MOP showed peak-to-peak voltages of up to 534 V and a maximum power density of 1.19 mW cm−2. In addition, the PTENGs showed excellent durability for 30 000 cycles, demonstrating as efficient power sources for charging electrolytic capacitors and for operating 200 green light emitting diode bulbs.
