dc.description.abstractSynthesis of (1-x)Bi<inf>0.47</inf>Na<inf>0.47</inf>Ba<inf>0.06</inf>TiO<inf>3</inf>-xBaSnO<inf>3</inf> ceramics (BNBT-xBS, where 0 ≤ x ≤ 0.05) was accomplished via a solid-state combustion approach. The influence of BaSnO<inf>3</inf> concentration on the phase structure, microstructure, dielectric, ferroelectric and strain properties was thoroughly examined. All specimens exhibited the coexistence of rhombohedral and tetragonal phases within a pure perovskite structure. The composition with x = 0.01 demonstrated optimal electrical properties, achieving a dielectric constant (ɛ<inf>m</inf>) of 6199, a maximum polarization (P<inf>max</inf>) of 41.86 μC/cm<sup>2</sup>, a maximum strain (S<inf>max</inf>) of 0.34% and a normalized strain (d<inf>33</inf>*) of 489 pm/V. The ceramic powder of BNBT-0.01BS was incorporated into a PDMS matrix at concentrations ranging from 0 to 30 wt%. The hybrid PENG/TENG devices achieved their largest electrical output at a BNBT-0.01BS loading of 20 wt%, recording a voltage of 92 V and a current of 0.50 μA. This work outlines a fabrication and development method for composite films with BNBT-0.01BS with PDMS polymers for high-efficiency nanogenerators, playing an important role in improving future energy harvesting technologies.
