Abstract

Abstract

Polymer piezoelectric materials polyvinylidene fluoride (PVDF) and its copolymers P(VDF-TRFE) and P(VDF-HFP) are typical organic polymer materials with piezoelectric properties. Currently, these materials attract great attention in academic and application area for their good mechanical properties, corrosion resistance, biocompatibility and easy processing. However, compared with the traditional inorganic piezoelectric ceramic materials, the piezoelectric constant of polymer piezoelectric materials is still relatively low, so improving the piezoelectric properties of such polymer piezoelectric materials has become one of the research hotspots at home and abroad. In this paper, the methods of improving the piezoelectric properties by combining PVDF and its copolymers with different functional materials at national and international levels in recent years are summarized, and the advantages and disadvantages of different types of fillers doped with different polymer piezoelectric materials and their development trends are prospected.
