Polyvinylidene difluoride piezoelectric electrospun nanofibers: Review in synthesis, fabrication, characterizations, and applications

Abstract

This review article highlights the methods and principles used for PVDF nanofiber creation and the use of these nanofibers in different fields by utilizing its piezoelectric performance, etc. The studies include different techniques to improve the alignment and piezoelectric behavior of nanofibers. The pressure versus sensitivity behavior of PVDF substrate is thoroughly analyzed. The optimum conditions (of experimental parameters) of the electrospinning technique are carefully studied to improve the structure, alignment, and performance of the generated nanofiber mats. In addition to experimental methods, the preparation of nanocomposites with carbon nanotubes (CNTs) also can improve the structure, alignment, and piezoelectric performance. The characterization tools used for the analyses of fabricated nanofibers are also discussed, in addition, to analyze the piezoelectric results of the targeted nanocomposite.
