Polyvinylidene fluoride (PVDF) is a specialist thermoplastic fluoropolymer with very good mechanical, chemical and thermal properties. Additionally, PVDF shows piezoelectric, pyroelectric, and ferroelectric properties. Antimony sulfoiodide (SbSI) nanowires (lateral dimensions of 10 nm - 100 nm and lengths up to a few micrometres) are also piezoelectric compound with one of the best electromechanical and piezoelectric coefficient (k33=0.9 and dV=0.9∙10-9 C/N). SbSI nanowires have been added to improve piezoelectric properties of PVDF. The prepared SbSI nanowires were bound with PVDF in a mass ratio of 15:85, which was the fibre formation input with the addition of SbSI nanowires at different take-up velocities. An active layer of nanogenerator was prepared from the fabricated PVDF/SbSI nanowire composite. The preliminary investigations of compression and vibrations, allowed for the determination of the composites open circuit voltage 1.2 Vp-p and 2.5 Vp-p, respectively. Generated powers under impact have reached values PS=408.8(52) μW/cm2 and PV=3.464(53) mW/cm3, respectively.Graphical abstract
