| description | <p dir="ltr">The need for flexible and wearable devices is quite great in the modern era of advanced electronics and the Internet of Things (IoT). Here, we present a poly(vinylidene fluoride) (PVDF)/Barium Titanate–Molybdenum Disulfide (BaTiO<sub>3</sub>–MoS<sub>2</sub>) composite-based flexible piezoelectric nanogenerator (PENG) with an improved electroactive phase. The electroactive, β-phase of the PVDF is shown to increase with the addition of BaTiO<sub>3</sub>–MoS<sub>2</sub> fillers as a result of the filler’s good interfacial interaction with the polymer matrix. The improved electroactive phase in the PVDF matrix was confirmed by the X-ray diffraction method and FTIR analysis of the composite films. The uniform dispersion of filler particles in the polymer matrix was confirmed by a scanning electron microscopy analysis. The developed piezoelectric nanogenerator device generated peak-to-peak output voltage of 4.9 V with a high dielectric constant of 22 and a low dielectric loss of 4.7. The fabricated gas sensor can perform at room temperature and exhibits good gas sensing performance toward the NH<sub>3</sub> gas. It was found that, compared to all other samples, the composite PVDF/BaTiO<sub>3</sub>–MoS<sub>2</sub> films had a high level of sensitivity. Additionally, the composite films showed response and recovery times of 11 and 17 s. The composite based on PVDF/BaTiO<sub>3</sub>–MoS<sub>2</sub> is a suitable material for NH3 sensor applications.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Materials Science: Materials in Electronics<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s10854-024-12400-2" target="_blank">https://dx.doi.org/10.1007/s10854-024-12400-2</a></p> |
