Triboelectric nanogenerators (TENGs) are flexible, efficient, and cost-effective energy harvesters. Here, we develop high-performance ferroelectric-assisted TENGs using electrospun fibrous surfaces based on P(VDF-TrFE) with dispersed BaTiO3 (BTO) nanofillers in either cubic (CBTO) or tetragonal (TBTO) form. three types of tribo-negative surface (pristine P(VDF-TrFE), P(VDF-TrFE)/CBTO P(VDF-TrFE)/TBTO) contact PET were investigated output increased progressively from pristine (0.75 W/m2) to CBTO (2 TBTO (2.75 W/m2). Accounting for pressure, the max (Voc = 315 V & Jsc 6.7 µA/cm2) is significantly higher than having spin-coated P(VDF-TrFE)/BTO. It hypothesized that electrospinning increases dipole alignment due high applied voltages, but also aids formation a highly oriented crystalline β-phase via uniaxial stretching. Essentially, tribo-charge transfer boosted potential owing enhanced ferroelectric polarization. P(VDF-TrFE)/TBTO produced even though permittivity nearly identical. Thus, it shown BTO fillers boost output, not just by increasing permittivity, enhancing crystallinity amount (as more present greater amounts). Finally, TENG was integrated flexible graphene electrode-based supercapacitor produce self-charging system capable charging 1.25 5 min. These results demonstrate this technology can be valuable wearable applications where power efficient flexibility paramount.
