초록 Composite nanofibers based on piezoelectric nanoparticles have been investigated in terms of their performance as energy harvesters. Perovskite nanoparticles of a few tens of nanometers in diameter were first prepared by a combustion synthesis technique using polyacrylic acid (PAA) as a fuel. Surface modification of nanoparticles by tetradecylphosphoric acid (TDPA) was carried out prior to the electro-spinning process. This treatment improves their dispersion and adhesion with poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] polymer. Location-dependent piezoelectricity measurement of the resultant fibers concludes that the region of embedded PZT or NKN filler particles exhibit greater piezoelectricity than the polymer matrix region. The energy harvesting performance of flexible nanogenerators demonstrated a few voltage outcome with > 100 nA output current.
