Study on the polarization process for piezoelectric nanofibrous layers

This paper deals with the optimization of the piezoelectric performances of nanofibrous membranes. Both ceramic and polymeric piezoelectric nanofibers are manufactured via electrospinning and polarized in order to align the ferroelectric domains and enhance the piezoelectric response of the mats. By investigating the electrical properties of the embedding mediums where the nanofibers were immerged during the polarization, it is possible to identify a proper configuration that maximize the dipoles alignment. The measured piezoelectric responses of the produced nanofibrous mats result comparable with commercial stiff piezoelectric samples ones.
