dc.description.abstractPiezoelectric composite nanofibers based on (Na-0.5,K-0.5)NbO3 (NKN) nanoparticles embedded in poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] polymer are investigated in terms of their performance as nanogenerators. Perovskite NKN nanoparticles with similar to 30-105 nm were separately prepared by combustion synthesis using polyacrylic acid (PAA) as a fuel. Surface modification of nanoparticles by tetradecylphosphonic acid (TDPA) was essential to secure proper adhesion with the polymer in the nanofibers prepared by electrospinning. Location-dependent piezoelectricity measurements confirmed that the region of embedded NKN filler particles exhibited better piezoelectricity than the P(VDF-TrFE) matrix region. Energy harvesting performance of the flexible composite nanogenerator demonstrated similar to 0.98 V output voltage and similar to 78 nA output current, which were enhanced depending on the volume fraction of the NKN nanoparticles dispersed in the polymer.
