Effect of zinc oxide on piezoelectric properties of polyvinilidyn floride/polydiacetylen/zinc oxide electrospun composite nanofibers

AbstractAmong smart materials, piezoelectric polymeric materials have a relatively high electrical response to mechanical stimuli, and diacetylenes are highly sensitive to color-changing materials. In this study, by combining the polymers of polyvinylidene fluoride (PVDF) and 10,12-pentacosadinoic acid and adding 1, 2, 3, 6, 9, 12, 15 and 18% zinc oxide (ZnO) nanoparticles to their solution, three component composite nanofibers were electrospun and their piezoelectric property were investigated.The results show that the presence of zinc oxide caused the formation of beads in the structure, but it caused a decrease of about 45%-60% in the average diameter of the samples compared to the PVDF/PDA samples. In these samples, in the best case, the piezoelectric property showed a maximum increase of about 12 times compared to the PVDF/PDA sample.According to the other results of various tests, the sample containing up to 3% ZnO enhances the piezoelectric performance of the PVDF/PDA dual response nanofibrous piezoelectric-chromic sensors.Keywords: Smart materialspiezoelectricZinc OxidePolyvinylidene fluoridePoly diacetyleneElectrospinningComposite Nanofiber Disclosure statementNo potential conflict of interest was reported by the author(s).
