Thin Flexible PVDF/ZnO Nanofibers as a Piezoelectric Sensor

Piezoelectric nanocomposites made of electrospun polymer nanofibers could be easily produced withhigh flexibility and acceptable sensitivity which is attractive in many applications. In this study, theelectrospinning of polyvinylidene fluoride (PVDF) at the nanoscale leads to the preparation ofuniform nanofibers with a high piezoelectric property. PVDF nanofibers with an average diameter of۲۱۹±۶۵ nm exhibited a sensitivity of ۲۶±۴ mV. In the presence of only ۰.۵ wt% zinc oxide (ZnO)nanoparticles, the sensitivity increased by about ۵۴% and reached ۴۰±۱۰ mV. The nanocompositedeveloped in this work can present its potential in different smart material systems.
