摘要：

We report high-performance flexible nanogenerators (NGs) based on a composite thin film, composed of hemispherically aggregated BaTiO3 nanoparticles (NPs) and poly(vinylidene fluoride-co-hexafluoropropene) P(VDF-HFP). The hemispherical BTO-P(VDF-HFP) clusters were realized by a solvent evaporation method, which greatly enhanced piezoelectric power generation. The flexible NGs exhibit high electrical output up to similar to 75 V and similar to 15 mu A at the applied force normal to the surface, indicating the important role of hemispherical BID clusters. Besides, the durability and reproducibility of the NGs were tested by cyclic measurement under bending stage, generating the output of similar to 5 V and similar to 750 nA. The approach we introduce here is simple, cost-effective, and well-suited for large-scale high-performance flexible NG fabrication.
